The area of a rectangle is 32m squred. The length is 2 m and the width is 2 times an unknown number added to 4. Find the number and the length of the rectangle.

Question

32m²

Answer 1

Let x = the unknown number

width = 2x + 4

a = lw

32 = 2(2x + 4)

16 = 2x + 4

12 = 2x

6 = x

length = 2(6) + 4 = 16 meters
