Sagot :
The area of the first plot is (7.5)² square feet, and the area of the
other one is (5.7)² square feet.
a). If sod costs 'y' dollars per square foot, then the cost for enough
sod to do the sod job is
Cost = (7.5² + 5.7²) y .
b). If sod costs $3.25 per square foot, then
Cost = (7.5² + 5.7²) x ($3.25) =
(56.25 + 32.49) x ($3.25) =
(88.74) x ($3.25) = $288.405
Rounded to the nearest dollar, that's $289.00 .
