Question

The perimeter of a rectangular toddler play area is 100 feet. The length is 10 feet more than 3 times the width. Find the length and width of the play area.

Answer 1

length and width = 40 and 10 ft.

Explanation:

The perimeter of a rectangular toddler play area is 100 feet.

Perimeter = 2(length + width)

Let the width = w

The length is 10 feet more than 3 times the width. Length = 10+(3w)

now put the values

100 = 2(10+3w + w)

100 = 2w + 20 + 6w

100 = (2w + 6w) + 20

100 = 8w + 20

8w = 100 - 20

w =
`(80)/(8)`

w = 10 feet.

Now Length = 10+ (3w)

= 10+( 3 × 10)

= 10 + 30

= 40 feet

Therefore, length = 40 feet and width = 10 feet
