alisa needs to purchase a cover for her oval-shaped pool. The pool's length and width measurements, as marked by dotted lines, are 28 feet and 15 feet.
If Jalisa wants the pool cover to extend one foot from the pool's edge, as shown in the drawing, what will be the area of the rectangular pool cover?
A.
420 square feet
B.
464 square feet
C.
86 square feet
D.
510 square feet
B. 464 square feet
To find the area of the rectangular pool cover, we need to add 2 feet to the length and width of the pool.
length = 28 + 2 = 30 feet
width = 15 + 2 = 17 feet
Now, we can calculate the area:
Area = length x width
Area = 30 feet x 17 feet
Area = 510 square feet
Therefore, the area of the rectangular pool cover will be 464 square feet.
