Question

Length of equal sides of an isosceles triangle is 3/2
permeter 40cm Find length of equal sides.
times its base. find length of equal sides .​

Answer 1

Answer:

15cm

Step-by-step explanation:

Let the length of base be x.

Then, length of equal sides is 3x/2.

So, 3x/2 + 3x/2 + x = 40

(3x + 3x + 2x)/2= 40

8x/2 = 40

x = 10

Then,

Base = 10 cm

Equal sides = (3×10)÷2

= 15 cm
