Assuming the shape is a triangle, the area is 11.40 sq ft, approx.
(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
Area of a triangle = (base x Height)/2 = 7 ft x 15 ft/2 = 105/2 sq ft= 52.5 sq ft
Length times width.
The answer depends on the shape of the driveway, and its dimensions.
Length times width. 10x12 room is 120 sq. ft.
Area = 0.5*base*height = 48 sq ft
Area = 0.5*Base*Height = 36 sq ft
Area = 0.5*Base*Height = 9 sq ft
A gallon of average paint will cover about 300 sq. ft. -Now you figure out your room dimensions in sq. ft.
Figure $80 to $150 a sq foot. 7000 sq ft @ $80/sq ft = $560,000
Using Pythagoras' theorem its height is 8.660254038 Area = 1/2*10*8.660254038 = 43.30127019 or 43 sq ft to the nearest sq ft
