The equation you can use to solve for the width 2w + 2(w - 2.3) = 53

Which equation can you use to solve for the width

From the question, we have the following parameters that can be used in our computation:

Perimeter = 53

Length = 2.3 units less than the width

This means that

Width = 2

Length = w - 2.3

The perimeter of a rectangle is calculated as

P = 2 * (L + W)

Substitute the known values into the equation

2w + 2(w - 2.3) = 53

Hence, the equation is 2w + 2(w - 2.3) = 53

Question

A rectangle has a perimeter of 53 units and the length is 2.3 units less than the width

Which equation below can you use to solve for the width, w, of this rectangle?

A=2w + 2(w-2.3) =53

B=2(2w) + 2.3w = 53

C=2w + 2 (w+2.3) = 53

D=2w + 2w + 2.3
