Question

What is the perimeter of a rectangle that has a length of 13x + 9 and a width of 7x + 4? *

Answer 1

Given the rectangle that has length of ( 13x + 9 ) and a width of (7x + 4)

the perimeter of the rectangle = 2 * ( length + width )

So,

The perimeter = 2 * [ (13x + 9) + ( 7x + 4) ]

= 2 * ( 13x + 9 + 7x + 4)

= 2 * ( 20x + 13 )

= 2 * 20x + 2 * 13

= 40x + 26

So, the perimeter of the rectangle = 40x + 26
