A homeowner wants a carpet three room that measure 12ft x 12ft, 10ft x 14ft, and 21ft x 20ft

How many square yards should be ordered rounded to the nearest tenth?

12 x 12 = 144 ft^2

10 x 14 = 140 ft^2

21 x 20 = 420 ft^2

144+140+420 = 704 ft^2

yards are one NINTH that amount because there are 3 feet in a yard and 3^2 ft^2 in a yd^2

Therefore,

704/9 = 78.2 square yards

so it would be solid 80 rounded to the nearest tenth

No, 78.2 The .2 is to the nearest tenth.

Utility poles are set every 30 meters. How many poles will set in one mile if one was set at the beginning of the mile??
