Question

Ratio of three sides of a triangles is 2:5:7. The perimeter of the triangles is 98cm. Find

the sides of the triangle​

Answer 1

Answer:

Step-by-step explanation:

2x+5x+7x=98

x=6

sides are 12,30,42

Answer 2

Given that ratio of three sides of triangle are 2:5:7 and perimeter is 98cm.

We have to find the sides of triangle.

let the three angles of triangle be 2x, 5x, and 7x

Perimeter of triangle = sum of all sides

⇒ 98 = 2x + 5x + 7x

⇒ 98 = 14x

⇒ 98/14 = x

⇒ 7 = x

or x = 7cm

2x = 2×7 = 14cm

5x = 5 × 7 = 35cm

7x = 7 × 7 = 49cm

Hence, the sides of the triangle are 14cm, 35cm, and 49cm.
