Question

The perimeter of a rectangular dining room is 22 meters. The dining room is 3 meters wide. How long is it?​

Answer 1

8 meters

Explanation:

perimeter of a rectangular figure = 2( length + width)

=> 22 = 2 ( length + 3)

• dividing both sides by 2

=> 11 = length + 3

• subtracting 3 from both sides

=> length = 8
