Question

Perimeter of an isosceles triangle is 16 cm. If length of the unequal side is 4 cm. Find the length of equal sides.

Answer 1

Answer:

perimeter of an isosceles triangle = a+b+c

=>14= 4 + 2b

=> 2b = 14-4

=> 2b= 10

=> b = 5

Therefore b= c two equal sides of an isosceles triangle.

Therefore the Sides are b= 5 cm

c= 5 cm.
