Robert is replacing sod in two square-shaped areas of his backyard. one side of the first area is 7.5 feet. one side of the other area is 5.7 feet. the sod costs y dollars per square foot. (hint: area of a square is l x w) write an expression to show how much robert will spend on sod.

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
