Solution
(a) To find the perimeter of a rectangle, you add up all the sides. The formula is P = 2(l + w) where l is the length and w is the width. In this case, the length is 86yd and the width is 68yd. So, the perimeter would be 2(86 + 68) = 2(154) = 308yd.
The area of a rectangle is found by multiplying the length by the width. The formula is A = lw. So, the area would be 86yd * 68yd = 5856yd^2.
So, the perimeter is 308yd and the area is 5856yd^2.
(b) The amount of chain needed to surround the lot would be determined by the perimeter of the lot. So, the perimeter would be used.
(c) The amount of pavement needed to cover the lot would be determined by the area of the lot. So, the area would be used.
