The area of a rectangle is 42 ft squared, and the length of the rectangle is 5 ft more than twice the width. Find the dimensions of the rectangle. length and width.

Width =

Step-by-step explanation:

Given,

Area of rectangle =

Width = X

Length = 2x + 5

Now,

Either

Or,

Negative value can't be taken.

So, width =

Again,

Finding the value of length,

Length =

Length = 12 ft

length = 12 ft, width = 3.5 ft

Step-by-step explanation:

w = width

l = length = 2w + 5

A = wl = w(2w + 5) = 42

2w² + 5w - 42 = 0

(w + 6)(2w - 7) = 0

w + 6 = 0, w = -6 (dimension cannot be negative)

2w - 7 = 0, w = 3.5

l = 2(3.5) + 5 = 12
