Plzz solve it.... ?!

Answer»

$\huge\frak{AnswEr :}$

Given Parameters :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Perimeter = 30 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Length of EQUAL sides = 12cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Let us assume that the third SIDE of isosceles TRIANGLE be x cm.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\underline{\sf \bigstar \: According \: to \: the \: question :}} \\ \\$

$\implies\sf \:x + 12 + 12 = 30 \\ \\ \\ \implies\sf \:x + 24 = 30 \\ \\ \\ \implies\sf \:x = 30 - 24 \\ \\ \\ \implies \large{ \boxed{\frak{ \purple{ \:x = 6}}}} \\ \\$

⠀__________________________

Now,

⠀⠀⠀⠀⠀⠀⠀⠀⠀

By using HERON's formula :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\implies\sf \: s = \dfrac{a + b + c}{2} \\ \\ \\ \implies\sf \: s = \dfrac{Perimeter}{2} \\ \\ \\ \implies\sf \: s = \frac{30}{2} \\ \\ \\ \implies \large{ \boxed{ \frak{\pink{\: s = 15}}}} \\ \\$

⠀__________________________

We know that,

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\implies\sf \: Area \: of \: \triangle = \sqrt{s(s - a)(s - b)(s - c)} \\ \\ \\$

Substituting the values :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\implies\sf \: Area \: of \: \triangle = \sqrt{15(15 - a)(15 - b)(15 - c)} \\ \\ \\ \implies\sf \: Area \: of \: \triangle =\sqrt{15(15 - 12)(15 - 12)(15 - 6)} \\ \\ \\ \implies\sf \: Area \: of \: \triangle = \sqrt{15 \times 3 \times 3 \times 9} \\ \\ \\ \implies\sf \: Area \: of \: \triangle = 3 \times 3 \times \sqrt{15} \\ \\ \\ \implies\sf \: Area \: of \: \triangle = 9 \times \sqrt{15} \\ \\ \\ \implies\sf \: Area \: of \: \triangle = 9 \times 3.88 \\ \\ \\ \implies \large{ \boxed{ \frak{\blue{ \: Area \: of \: \triangle = 34.92 \: cm {}^{2} }}}} \\ \\$

$\therefore \: {\underline{\sf{ Area \: of \: the \: isosceles \: \triangle \: is \: \bf \: 34.92 cm{}^{2}. }}} \\$

9.	Find the cost of fencing a square park ofside 5000 cm at the rate of 10per m.
Answer» Given : Side of Square park = 5000 CM To find : Cost of fencing @ rate of Rs. 10 per m. Solution : Here, the side of square is in cm. ( 5000 cm Then we have to CHANGE it in m because as per the question, the cost of fencing is Rs. 10 per m. To change cm to m, DIVIDE the value by 100. ( 5000/100 ) We know that, 1000 cm = 10 m So, 5000 cm = 50 m. Side of square park = 50 m To find Perimeter of Square : PERIMETER of Square = 4 × side ⟶ 4 × side ⟶ 4 × 50 ⟶ 200 ∴ Perimeter of Square park = 200 m². Now, we have to find the cost of fencing square park. Cost of Fencing = Perimeter × cost per m ⟶ 200 × 10 ⟶ 2000 ∴ Cost of Fencing the SQAURE park = 2000 Rs. _____________________

Find the cost of fencing a square park ofside 5000 cm at the rate of 10per m.

Answer»

Given :

Side of Square park = 5000 CM

To find :

Cost of fencing @ rate of Rs. 10 per m.

Solution :

Here, the side of square is in cm. ( 5000 cm Then we have to CHANGE it in m because as per the question, the cost of fencing is Rs. 10 per m.

To change cm to m, DIVIDE the value by 100. ( 5000/100 )

We know that, 1000 cm = 10 m

So, 5000 cm = 50 m.

Side of square park = 50 m

To find Perimeter of Square :

PERIMETER of Square = 4 × side

⟶ 4 × side

⟶ 4 × 50

⟶ 200

∴ Perimeter of Square park = 200 m².

Now, we have to find the cost of fencing square park.

Cost of Fencing = Perimeter × cost per m

⟶ 200 × 10

⟶ 2000

∴ Cost of Fencing the SQAURE park = 2000 Rs.

42.

If the difference between the sides of a rightangled triangle is 3 cm and its area is 54 cm²;find its perimeter.

Answer»

the DIFFERENCE between the BASE and height is 3cm3cm, let AB =xcm=xcm and AC =(x+3)CM=(x+3)cm

Area of triangle =12×base×height=54=12×base×height=54 sq cm

12×x×(x+3)=5412×x×(x+3)=54

=>x2+3x=108=>x2+3x=108

x2+12x−9x−(12×9)=0x2+12x−9x−(12×9)=0

Solving it x=9;−12x=9;−12

Since SIDE cannot be negative, AB =x=9cm=x=9cm

AC =x+3=12cm=x+3=12cm

Since the third side BC is the hypotenuse , BC2=92+122=225BC2=92+122=225

Hence, BC =15cm=15cm

Perimeter of the triangle == Sum of all sides =15+9+12=36cm=15+9+12=36cm
