Question

The ares of a rectangle is 46 square inches, if the length is 4 times the width , the find the dimensions of the rectangle.

Answer 1

`√(11.5) =w` (Width)

`4√(11.5)= Length`

Explanation:

Area of a rectangle: 46 = w(L)

L = 4w

Substitute

46 = 4
`w^(2)`

Divide both by 4

`11.5=w^(2)`

`√(11.5) =w` (Width)

`4√(11.5)= Length`
