Question

A blackboard has an area of 28ft and a perimeter of 22 ft. What are the dimensions of the board?

Answer 1

width and height their is no depth

Answer 2

Hey there!

Area is multiplying the width and the length, so check what two numbers equal 28 . . .

4 x 7 =  28 (area)


4 + 4 = 8

7 + 7 = 14

8 + 14 = 22 (perimeter)

The dimensions are 4 by 7 ft.

Hope this helps you.
Have a great day!
