Answer:
8x-2
Step-by-step explanation:
perimeter=2l+2w
perimeter= 2(2x+3)+2(2x-4)
=4x+6+4x-8
=8x-2
The perimeter of the rectangle with width (2x + 3) and length (2x - 4) is 8x - 2
Given:
Perimeter of a rectangle = 2(length + width)
= 2{(2x - 4) + (2x + 3)}
= 2(2x - 4 + 2x + 3)
= 2(4x - 1)
= 8x - 2
Therefore, the perimeter of the rectangle is 8x - 2
