It costs a family $324 to buy a 10-ft-by-12-ft rectangular rug. At this rate, what is the approximate cost of a 15-ft-by-18-ft rectangular rug?
$324 for a 120ft^2 rug
$2.7 for each square foot (1ft^2)
x for a 270ft^2 rug
270 x $2.7 = $729
The approximate cost of a 15-ft-by-18-ft rectangular rug is $729.
It costs a family $324 to buy a 10-ft-by-12-ft rectangular rug.
Means for \(10\times12=120\) square feet, the cost of rug is $324
So, for 15-ft-by-18-ft or @@MATH_TOKEN_1@@ square feet of rug, the cost will be =
@@MATH_TOKEN_2@@
Therefore, the approximate cost of a 15-ft-by-18-ft rectangular rug is $729.
