Question

The perimeter of an isosceles triangle is 37 cm. If two of its equal sides measure 10 cm each find the length of the third side of triangle.

Answer 1

Answer:

Let the third side as - x

Perimeter of triangle is = 37

measures two equal side each = 10 cm

10cm+ 10cm + x = 37

20+ x = 37

x= 37-20

= 17

Third side = 17cm

Answer 2

Let the third side as - x

Perimeter of triangle is = 37

sum of two equal side = 10

10÷2 = 5

5cm+ 5cm + x = 37

10+ x = 37

x= 37-10

= 27

Third side = 27 cm
