Question

find the length of each side of an isosceles triangle whose perimeter is 18 CM and length of the third side is 2cm

Answer 1

Answer:

Sides are 2 cm , 8 cm and 8 cm.

Step-by-step explanation:

• Let the equal sides be x .

A/Q, x + x + 2 = 18

2 x + 2 = 18

2 x  = 16

x = 8.

Answer 2

Given: Third side of the isosceles triangle is 2cm and perimeter is 18cm.

To find: The length of the isosceles side.

Answer:

An isosceles triangle is a triangle with 2 equal sides.

Let's  suppose one of the isosceles side is x. The other side will also be x as two sides are equal in an isosceles triangle.

x + x + 2 = 18cm

2x + 2 = 18cm

2x = 18 - 2

2x = 16cm

x = 16/2

x = 8cm

Therefore the sides are 8cm, 8cm and 2cm.

Hope it helps :)
