Question

The length of a rectangle is 3 less than twice the width of the rectangle. If the area is 70, which of the following equations could be used to find the width (x)?

a) 2x - 3 = 70
b) 2x + 3 = 70
c) x + 3 = 70
d) 2x - 3 = 140

Answer 1

The correct equation to find the width of the rectangle when the length is three less than twice the width and the area is 70 is (2x - 3) × x = 70.

Step-by-step explanation:

The question involves finding the width of a rectangle when given the relationship between its length and width, and the area of the rectangle.

To identify the correct equation to find the width (x), we can set up an equation using the information provided - the length of the rectangle is three less than twice the width, and the area is 70 square units.

So, let the width be x units. The length of the rectangle would then be 2x - 3 units.

The area of a rectangle is found by multiplying the length by the width, which gives us the equation (2x - 3) × x = 70.
