Question

The area of a rectangular region is 7.26 × 10* square feet. The length of the rectangular region is 1.21 × 10° feet. How much

does it cost to surround the region with a border that costs $0.80 per foot?

Answer 1

$283.2

Explanation:

Area of the order = Length * Width

7.02×10^3 = 1.17×10^2 * Width

7020 = 117W

W = 7020/117

W = 60feet

The perimeter of the border = 2(L+W

P = 2(117+60)

P = 2 * 177

P = 354 feet

If a border cost $0.80 per foot, 354 feet long border will cost 0.80 * 354 = $283.2
