Question

a rectangle is 8 feet long. Its width is represented by "seven plus x feet.",Which expression represents the area, in square feet, of the rectangle.

Answer 1

A= 8 * (7+ x)

Explanation:

since the area of a rectangle is l*b

l= 8 feet

b= 7+ x feet

thus a= 8*(7+x)

Answer 2

The square footage could be expressed as 8x + 56

Explanation:

To find this, we take the length and multiply by the width.

A = L*W

A = 8(x + 7)

A = 8x + 56
