The base of an isosceles triangle is 4 3 cm

Asked by admin @ 05/08/2021 in Math viewed by 278 People

Exercise 2.2 the base of an isosceles triangle is 4/3 cm. the perimeter of the triangle is 62/15 cm. what is the length of either sides of the remaining equal sides?

Answered by admin @ 05/08/2021

Base=4/3cm
Let the equal sides be x.
Perimeter=S1+S2+S3
62/15=x+x+4/3
62/15=2x+4/3
62/15-4/3=2x
(62-20)/15=2x
42/15/2=x
42/15×1/2=x
21/15=x
7/5=x

Thus,
Two equal sides = x = 7/5cm
