Answer:
The expression becomes for the Robert will spend on sod.
x = 56.25 y + 32.49 y
Step-by-step explanation:
Let us assume that the Robert will spend on sod = x
As given
Robert is replacing sod in two square-shaped areas of his backyard.
As given Formula in the question
Area of a square = L × B
Where l is the length and B is breadth .
(As in the case of the square all sides are equal.)
Thus
Area of a square = L × L
= L²
One side of the first area is 7.5 feet.
Area of square for first = 7.5 × 7.5
= 56.25 feet²
One side of the other area is 5.7 feet.
Area of square for other = 5.7 × 5.7
= 32.49 feet²
As given
The sod costs y dollars per square foot.
Thus the expression becomes
x = 56.25 y + 32.49 y
