How to find the area of the square whose side is 8 cm

Answer»

Given :

Side of a square = 8 cm

To find :

AREA of square

ACCORDING to the question,

As we know,

➞ Area of square = Side × Side

➞ Area of square = 8 cm × 8 cm

➞ Area of square = 64 cm²

So,the area of square is 64 cm².

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

MORE FORMULAS :-

Area of rectangle = Length × Breadth
Area of square = Side × Side
SURFACE area of a cube = 6a²
Surface area of cuboid = 2(lb + bh + HL)
Volume of cuboid = l × b × h
Total surface area of a hemisphere = 3πr²
Curved surface area of a cone = πrl

25.

1. Find the compound interest and amount ineach of the following:(i) P=3000, R = 5% p.a., Time = 2 years

Answer»

Answer:

RS.307.50

Step-by-step explanation:

Principal (P) = Rs.3000

Rate (R) = 5% p.a.

Time (n) = 2 years

Amount (A) = P (1 + R/100)ⁿ

=> A = 3000 (1 + 5/100)²

=> A = 3000 (21/20)²

=> A = Rs.3307.50

Compound Interest = Rs.(3307.50-3000) = Rs.307.50

A number consists of two digits. The product of the digits is 20. When 9 is added tothe number, the digits interchange their places. Find the number.

Answer»

Step-by-step explanation:

let the two digit no. be =10x + y

and it's 10 place digit = x and unit place digit = y

xy =20............(1)

(10x+y) + 9 = 10Y+ x............(2)

10x - x -10y + y +9 =0

9x - 9y + 9 =0

taking 9 common

x-y +1=0

using y=x +1 , put in eq 1

x × (x+1)=20

x^2+x - 20=0

${x}^{2} + 5x - 4x - 20 = 0$

x(x+5) - 4(x +5)=0

(x-4) (x+5)=0

x=4 , x can't be equal to-5 as in a number DIGITS can't be negative

y=x+1

y = 4+1 =5

no. =10x +y= 10×5+4=50+4 =54
