the width of a rectangle is 8 inches more than the length. The perimeter is 60. Find the length and width of the rectangle

Question

i have to find t  equation and answer to the equation. i just need help setting up the equation 

Answer 1

The formula for the perimeter of a rectangle is 2W + 2L, where W and L are the width and length. Since the perimeter is 60, we know that 60 = 2W + 2L

 

The width is 8 more than the length, so W = L+8

 

Now we can substitute the value of W in the first equation:

60 = 2(L+8) + 2L

 

Now you can solve for L, and then you can use that to find the value of W
