Answer 1

The area and perimeter of the rectangles are 2x^2 +11x - 21 and 6x + 8 respectively

Area and perimeter of rectangle

The formula for the area and perimeter of rectangle is expressed as;

A = length * width

P = 2(l + w)

Given the following

l = 2x + 3

w = x + 7

Substitute

A = (2x-3) (x+7)

A = 2x^2 + 14x - 3x - 21

A = 2x^2 +11x - 21

For the perimeter

P = 2(2x - 3 + x + 7)
P = 2(3x + 4)

P = 6x + 8

Hence the area and perimeter of the rectangles are 2x^2 +11x - 21 and 6x + 8 respectively
