Question

The width of a rectangle is 6x -5.5 feet and the length is 5.5x + 10 feet. Find the perimeter of the

rectangle.

Answer 1

23x + 9

Explanation:

Perimeter = 2*(length + width)

= 2*( 5.5x + 10 + 6x - 5.5)

= 2* (5.5x + 6x + 10 - 5.5) {Combine like terms}

5.5x and 6 are like terms & 10 and (-5.5) are like terms

= 2* (11.5x + 4.5)

= 2*11.5x + 2*4.5

= 23x + 9
