Ezra has a square brick patio. he wants to reduce the width by 6 feet and
increase the length by 6 feet.
What is the area of the square?
The area of the square is the measure of the space occupied by it. It is equal to the product of the measure of its two sides.
We need to write the expression for the new patio and the area of the new patio if the original patio measures 13 feet by 13 feet.
let x be the measure of the side of a square.
The length increased by 6 ft, so the new length=x+6.
The width decreased by 6 ft, so the new width=x-6.
The area is the product of length and width, so the new area is
l×w = (x+6)×(x-6)
Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft.
So, the area is (19 ft)×(7 ft) = 133 ft²
Hence, the area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².
