Answer:
Length=8 and width=6
Explanation:
The length of the rectangle is 4 less than twice the width, let l stand for length and w for width: l=2w-4
The perimeter is equal to 28 and the formula for the perimeter of a rectangle is 2l+2w: 28=2l+2w
Substitute l into the equation:
28=2(2w-4)+2w
28=4w-8+2w
28=6w-8
36=6w
w=6
Find for l:
l=2w-4
l=2(6)-4
l=12-4
l=8
