Question

The area of a rectangle is 105 cm² they would have a rectangle is 7 centimeters what is the perimeter of the rectangle

Answer 1

P = 2(15 cm) + 14 cm =44 cm

Explanation:

If the length of the rectangle is 7 cm, then the area would be A = 105 cm² = (7 cm)(width), and in turn the width would be (105 cm²) / (7 cm) = 15 cm

and the perimeter, P, would be P = 2(width) + 2(7 cm) = 2w + 14 cm.

But we know already that width = w 15 cm.

Thus, the perimeter of the rectangle is P = 2(15 cm) + 14 cm =44 cm
