Answer 2

Answer:

The length of each equal side is 4.4 centimetres.

Explanation:

We know that isosceles triangles are triangles with two equal sides.

Let x be an equal side.

Base of the triangle = $7.9cm$

Perimeter = $16.7cm$

∴ x + x + 7.9 = 16.7

2x + 7.9 = 16.7

2x = 16.7 - 7.9

2x = 8.8

x = 8.8 ÷ 2

x = 4.4.

The length of each equal side is 4.4cm.
