Question

Q.9. The base of an isosceles triangle is 18 cm the perimeter of the triangle is 28cm what is the length of either of the remaining equal sides? ​

Answer 1

Answer:

Length of remaining equal sides = 5 cm i.e. (5 + 5 = 10 cm)

Step-by-step explanation:

Given,

Perimeter of Triangle = 28 cm

Base = 18 cm

Let, length of equal side of isosceles triangle be x

( x + x = 2x)

Perimeter of Triangle = 18 + x + x

28 = 18 + 2x

28 - 18 = 2x

10 = x

2

x = 5cm
