The length of a rectangle is 3 inches more than its width, and its perimeter is 22 inches. Find the width of the rectangle.
1 answer:
Answer:
W = 4 in
Step-by-step explanation:
Here W is the width and L the length. Then L = W + 3 in.
The formula for the perimeter of a rectangle is P = 2W + 2L.
Thus, 22 in = 2(W) + 2(W + 3), which reduces to
11 in = W + W + 3 in, or
8 in = 2W, and W = 4 in
