Question

The perimeter of an isosceles triangle is 40 cm. The base is two-third of the
sum of equal sides. Find the length of each side

Answer 1

Answer:

a=12

b=16

Step-by-step explanation:

let the equal side and base be a and b respectively

b= 2a*2/3 = 4a/3

Perimeter of iso ∆ = 2a + b

40 = 2a + 4a/3

40 = 10a/3

a = 12

so, b = 4(12)/3 = 16
