68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
289 sqft (17 x 17 = 289)
1 acre = 43560.17 sqft divide that by 3 = 14520.06 sqft
1/2 ground is 1200 sqft. 1 ground in 2400 sqft.
21,780 sqft
269.23
1418 sqft = 131.74m2
2,800 sqft is 0.064 acre.
Base it off : 12" thick a yard of concrete will go 27sqft. 6" thick will go twice as many sqft so 54 sqft. 4" thick will go 3 times as many sqft so 81 sqft 2" thick will go 6 times as many sqft so 162 sqft and at 1" thick it will go 324 sqft. So at 5" thick...1 yard of concrete will go 67.5 sqft
1,000 sqft (40 x 50 = 1,000)
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
289 sqft (17 x 17 = 289)
That depends on the - or + values of 28x and 980 which have not been given
172 acres is 7,492,320 square feet. (43,560 sqft per acre).
100sqyd is 900sqft
1 acre = 43560.17 sqft divide that by 3 = 14520.06 sqft
There are 1,436 yards in 718 sqft because 1 yard = 3 feet, so 1 sqft = 3x3 = 9 square feet. To convert sqft to yards, divide the measurement in sqft by 9.
