First, we determine the area of the rectangular house by multiplying the length by the width. That is,
area of the house = (50 ft)(24 ft) = 1200 ft²
Given that all sides of the house should have the pathway, the length of the house plus the pathway should be 50+2x and the new width would be 24+2x. The new area minus the original area of the house should not be more than 345 ft². Thus, the equation would be,
(50+2x)(24+2x) - 1200 ≤ 345
False; a sphere has an infinite number of great circles.
Divide by 90%.
x = £55.56
The easiest way to figure this out is by finding out the price for 12 reams at the local store.
4 reams is 4.29 so 12 would be:
3*4.29 = 12.87
Subtract the prices:
12.87 - 9.89 = 2.98
So you save $2.98 by buying from the Wholesale Club.
360 tiles because you have to multiply 12x30.
