Question

A rectangles width is 4 less than its area and its length is 19. what is it’s width?

Answer 1

The width of the rectangle is $\frac{2}{9}$ unit

Step-by-step explanation:

The given is:

• A rectangles width is 4 less than its area
• Its length is 19 units

We need to find the width of the rectangle

Assume that the width of the rectangle is x units

∵ The area of the rectangle = length × width

∵ The width of the rectangle = x units

∵ The length of the rectangle = 19 units

∴ The area of the square = 19 × x = 19 x units²

∵ The width of the rectangle is 4 less than its area

- That means subtract 4 from the area to find the width

∴ x = 19 x - 4

- Subtract 19 x from both sides

∴ -18 x = -4

- Divide both sides by -18

∴ x = $\frac{-4}{-18}$

- Reduce the fraction by dividing up and down by -2

∴ x = $\frac{2}{9}$

The width of the rectangle is $\frac{2}{9}$ unit
