Question

Find the perimeter of the triangle given below.

• A. 150 cm
• B. 90.6 cm
• C. 690 cm
• D. 90.6 m

Answer 1

The correct option is A 150 cm

Perimeter of a triangle is equal to the sum of its three sides.
Sides of the triangle are 40 cm, 50 cm and 0.6 m long.

We know that,
1 m = 100 cm
$\therefore$ 0.6 m = 0.6 x 100
= 60 cm

Perimeter = 40 cm + 50 cm + 60 cm
= 40 cm + 50 cm + 60 cm
= 150 cm
