Question

Jalisa needs to purchase a cover for her oval-shaped pool. The pool's length and width measurements, as marked by dotted lines, are 31 feet and 15 feet.

Answer 1

Answer:

The area of the pool is: 365.025 squared feet

Step-by-step explanation:

Given

$L = 31$ --- Length

$W = 15$ --- Width

Required

The area of the pool

The area of an oval shape (i.e. the pool) is:

$Area = \pi ab$

Where

$a = \frac{L}{2}$

$b = \frac{W}{2}$

So, we have:

$Area = \pi * \frac{L}{2} * \frac{W}{2}$

$Area = \pi * \frac{31}{2} * \frac{15}{2}$

$Area = \pi * \frac{465}{4}$

$Area = \pi * 116.25$

$\pi = 3.14$

So:

$Area = 3.14 * 116.25$

$Area = 365.025$
