Question

The perimeter of an isosceles triangle is 10 ¾ cm . If one of its equal side is 2 ¾ cm ,the third side IS, *

Answer 1

4 cm

Explanation:

Given is an isosceles triangle. Therefore it's two sides will have equal lengths.

Let the length remaining sides be x cm.

`x + x + 2 (3)/(4) = 10 (3)/(4) \\ \\ 2x + (11)/(4) = (43)/(4) \\ \\ 2x = (43)/(4) - (11)/(4) \\ \\ 2x = (32)/(4) \\ \\ 2x = 8 \\ \\ x = (8)/(2) \\ \\ \huge \red{ \boxed{x = 4 \: cm \: }}`
