ANSWER:

BRO KNOWLEDGE about this RULE in ERROR.

GIVEN :-

• A diagonal of a quadrilateral is 40 m long and the perpendiculars to it from the opposite corners are 8 m and 10 m respectively.

Have to Find :-

• Find the area

Solution :-

As we know the formula of area of quadrilateral

(½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.

↬ ½ × d × ( sum of lengths )

Here ,

D = 40 m

Lengths = 8 m and 10 m respectively.

Therefore,

Substituting the VALUES in the above formula ,

↬ ½ × 40 × ( 8 + 10 )

↬ ½ × 40 × 18

↬ 40 × 9

↬ 360 m²

____________________________

★ Some Important Formulas ★

➤ Perimeter of Rectangle = 2( L + B )

➤ Perimeter of square = 4 × SIDE

➤ Perimeter of triangle = AB + BC + CA

➤ Area of Rectangle = L × B

➤ Area of Square = ( side ) ²

➤ Area of Rhombus = Product of Diagonal/2.

➤ Area of Parallelogram = Base × Height.

➤ Area of triangle = 1/2 × base × height .

Given data :

• MADHAVI bought a table cloth 2.25 m long and 1.75 m wide.

• She WANTED to put lace around table.

To find :

• How many meters of lace would Madhavi require.

• How much would lace cost if it cost ₹ 14.50 per metre

Solution : Let, shape of table be rectangle.

Now, according to given,

→ Length of table = 2.25 m

→ Breadth of table = 1.75 m

Now, we use formula of perimeter of rectangle,

→ Perimeter of rectangular table

= 2 ( Length + Breadth )

→ Perimeter of rectangular table

= 2 ( 2.25 + 1.75 )

→ Perimeter of rectangular table

= 2 * 3

→ Perimeter of rectangular table

= 6 metre

Now,

→ Cost of 6 metre lace

= ₹ ( 6 * 14.50 )

→ Cost of 6 metre lace

= ₹ 87

Answer : Hence, SIX metre of lace would Madhavi require. and cost of 6 metre lace is ₹ 87.

Answer:

In triangle sum of 2 sides must be greater than the 3rd side. So, the third > 10 - 8 = 2 and ALSO the third < 10 + 8 = 18. So, the answer is 2 < third side < 18. The third side lies between(2,18).

Step-by-step EXPLANATION:

TOTAL Age is given 93 Years

Ten Years Ago the ratio of their AGES was 2:3:4

Let,

Jiya age 2x+10

Kunal age 3x+10

Sagar age 4x+10

(2x+10+3x+10+4x+10) = 93 Years

9x+30 = 93 Years

9x = 93-30 Years

9x = 63 Years

x = 63/9 Years

x = 7 years

2x+10 = 2×7+10 = 24 Years

3x+10 = 3×7+10 = 31 Years

4x+10 = 4×7+10 = 38 Years

93 Years

Answer:

15 days

Step-by-step explanation:

let m is no of mens and w is no of womens

now 6 men and 9 women can do work in 10 days

6 men and 9 women 1 day work = 1/10

6m + 9W = 1/10

3(2m + 3w)= 1/10

2m + 3w = 1/30

now we REQUIRE work done by 4 men and 6 women

multiply 2 on both sides of above EQUATION

2(2m +3w) = 2/30

4m + 3w =1/15

4 men and 3 women 1 day work is 15 units

so, 4 men and 3 women can complete work in 15 days

CLASSIFICATION of algebraic expressions

Classification of algebraic expressionsMonomial: An algebraic expression containing only one term is CALLED a monomial. For example; 3X, -7, ⁵/₉ a²bc are all monomials. Binomial: An algebraic expression containing two terms is called a binomial. For example; x – 7, 5x + 9y, ab + care all BINOMIALS.

Answer:

ETNE QUESTIONS ONE one question DETE

Step-by-step explanation:

120+y = 180

linear pair

so , y = 180-120=60

x+y+60 = 180

(SUM OF ALL ANGLES OF TRIANGLES)

y=60

therefore,

x+60+60= 180

x= 180-120

x= 60

Such debates — about the MERITS of the decisions India has made in TACKLING Covid-19 — are now legion. Everything, from India’s early handling of foreign travellers and airport PROTOCOLS to testing strategies, ill-equipped healthcare workers, poor handling of migrant workers and MEAGRE support for the industry, is being debated threadbare in locked-down drawing ROOMS and overheated social media. It’s understandable when the nation is at war with a deadly invisible enemy — a virus. Panic-stricken citizens, confined to their home bunkers, are closely monitoring grim news flowing in from home and abroad. Infections and death counts are rising. Doctors are attacked. Healthcare staff demand masks and protective gears even as hotels and trains are converted into quarantine zones and hospitals.
