If the area of the fountain will be 18 square feet. Then the width of the fountain will be 3 feet.
What is a rectangle?
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
Cindy is designing a rectangular fountain in the middle of a courtyard. The rest of the courtyard will be covered in stone.
The part of the courtyard that will be covered in stone has an area of 246 square feet.
The area of the fountain will be
Area of fountain = area of the rectangle - 246
Area of fountain = 12 x 22 - 246
Area of fountain = 264 - 246
Area of fountain = 18 square feet
Then the width of the fountain will be
A = W x L
18 = W x 6
W = 18/6
W = 3 feet
