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 yards did Colton swim?

Answer 1

2(L+B)=124
2(L+20)=124
L+20=124/2=62
L=62-20=42 Ans.

Answer 2

Colton swam 42 yards

Step-by-step explanation:

Let the Length of pool be x

Width of pool = 20 yards

Perimeter of pool = 2(l+b)=2(l+20)

Colton swam once along the length of a pool that has a perimeter of 124 yd.

124 = 2(l+20)

62=20+l

62-20=l

42=l

Hence Colton swam 42 yards
