Answer:
The rectangle has a length of 15 cm and a width of 13 cm
Step-by-step explanation:
Let w represent the width of the rectangle, and let w + 2 represent the length of the rectangle.
Use the perimeter formula, P = 2l + 2w, and plug in the perimeter and w + 2:
P = 2l + 2w
56 = 2(w + 2) + 2w
Simplify and solve for w:
56 = 2w + 4 + 2w
56 = 4w + 4
52 = 4w
13 = w
Then, add 2 to this to find the length:
13 + 2
= 15
So, the rectangle has a length of 15 cm and a width of 13 cm.
