Question

7. The classroom is 987.3 centimetres long. The width is 295 centimetres less than the length. What is the perimeter of the classroom in metres?​

Answer 1

33.592 meters

Explanation:

The classroom is 987.3 cm in length, and the width is 295 less.

Finding the width 987.3-295=692.3

The classroom is 987.3 cm long and 692.3 cm wide.

Finding the perimeter,

987.3*2+692.3*2=3359.2 centimeters.

Since 1 centimeter is 0.01 meters,

the perimeter of the classroom is 33.592 meters.
