Question

The length of a rectangular garden is 5 meters shorter than twice it width, the area of its region is 150 square meters. Find the dimensions of the garden?

What is the formula?​

Answer 1

Explanation:

length = x - 5

width = 2x

2x(x-5) = 150 m^2

2x^2 - 10x = 150 m^2

2x^2 - 10x - 150 = 0

(x=11.51 or x = -6.513)

if you wanna check,

2(11.51) × (11.51-5) = 150

23.02 × 6.51 = 150

149.8602 = 150

I'm not sure if its correct though^^
