Question

the perimeter of a rectangular parking lot is 298m if the width of the parking lot is 67m what is its length?

the area of a rectangular pool is 4664m2 if the length of the pool is 88m what is its width?

Answer 1

P=298, W=67, L + W = 298/2 = 149

L = 149-67 = 82 meters long

2(82+67) = 2(149) = 298 meter perimeter

Area = 4664, L= 88

4664=LW = 88W

W = 4664/88 = 53 meters wide

53 x 88 = 4664
