Question

Colton swam once along the length of a pool that has a perimeter of 124 yd. the width of the pool is 20 yd. how many feet did colton swim?

Answer 1

42 yards. Hope this helps :)

Answer 2

Answer:

The answer is 126 feet.

Step-by-step explanation:

In order to determine the feet, first we have to determine the length of the pool and then we have to transform units from yd to feet.

We know the perimeter and there is a formula that relation the perimeter with the width and length.

Let:

W=width of the pool

L=Length of the pool

P=Perimeter of the pool

$P=2*W+2*L\\2*L=P-2*W\\L=\frac{P-2*W}{2} \\\\L=\frac{124-2*20}{2}\\L=42$

Then, we have to transform units from yd to feet.

$3 feet= 1 yd$

So, 42yd=126 feet
