Question

A rectangular garden has a width that is twice the length. The garden perimeter is 48 meters. What are the dimensions of the garden?

Answer 1

Answer:Width

= 10 meters

Length

= 15 meters

Explanation:

Given:

Width = x

Length = 2 x − 5

Perimeter = 50

Perimeter = 2 × length + 2 × width

Substitute: 50 = 2 ( 2 x − 5 ) + 2 ( x )

Simplify: 50 = 4 x − 10 + 2 x 50 = 6 x − 10 60 = 6 x = 10

Substitute (FINALLY)

Width: x = 10

So width = 10 meters

Length: 2 x − 5 = 2 ( 10 ) − 5 = 20 − 5 = 15

So length = 15 meters
