Answer 1

Answer:

The length is 10 inches and the width is 7 inches.

Step-by-step explanation:

A rectangle is shape with 4 sides where 2 pairs of sides are equal and form 4 perpendicular angles. 1 pair of sides is the width and is distance w. 1 pair of sides id the length and is 3 inches more than the width or 3 + w. The total distance around the shape is the perimeter. We know the perimeter is 34 inches. Add each side together and set it equal to 34. Then solve for w.

P = l + l + w + w

34 = 3 + w + 3 + w + w + w

34 = 6 + 4w

28 = 4w

7 = w

This means its length which is 3 inches longer is 7 + 3 = 10.
