Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side. Write an expression to represent the area of Bills mural.
(10-2y)(10-2y)
To find the expression representing the area of Bill's mural, we need to consider that Bill's mural measures y feet shorter on each side compared to Ociel's mural.
Since Ociel's mural is a square measuring 10 feet on each side, the area of Ociel's mural is given by length × width, which is 10 × 10 = 100 square feet.
Now, since Bill's mural measures y feet shorter on each side, the length and width of Bill's mural would be (10 - y) feet. Therefore, the area of Bill's mural is given by the expression:
Area of Bill's mural = (10 - y) × (10 - y) square feet
So, the expression representing the area of Bill's mural is (10 - y)².
