Question

Question 1.
Sides of a triangle are in a ratio of 12:17:25 and its perimeter is 540 cm its area?

Answer 1

Answer:

Let one side be 12x

Let second side be 17x

Let third side be 25x

A.T.Q

Perimeter of this triangle = Sum of all sides

540 cm = 12x + 17x + 25x

540 cm / 54 = x

x = 10 cm

Sides of the triangle will be 120 cm, 170 cm, and 250 cm.

Using, Hereon's formula u will get the area.

Therefore, the area of this triangle is 9000 cm2.

Answer 2

Answer:

a:b:c

12x:17x:25x

x=10

120,170,250

s=a+b+c/2

A=√s(s-a)(s-b)(s-c)

A=√270×150×100×20

9000 cm²
