Question

The perimeter of a rectangle is 100 centimeters. It’s width is 9 centimeters. Find it’s length

Answer 1

41.

Explanation:

A rectangle has four sides, opposite sides having the same length.

If one of the sides is 9 cm, then the side opposite to it would also be 9 cm. This leaves 82 cm left in the perimeter, 41 for each remaining side.
