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.

32.49y+56.25y

Take 5.7*5.7=32.49
Take 7.5*7.5=56.25
Those are the areas of each square shaped areas in Roberts backyard. Multiply each by then cost of y and then add both together...
