Question

The width of a rectangle is 1 units less than the length. The area of the rectangle is 56 units. What is the width and units of the rectangle?

Please show work!

Answer 1

The area of a rectangle is given by:

(Area)=(length)*(width)

A=L*W

In this case, we know the area, and we know the relationship between length and width:

A=56 units1

W=L-10

We can substitute this information into the original equation for area:

A=L*W

(56 units1)=L*W [substituting the given area for A]

(56 units1)=L*(L-10) [substituting the given relationship between length and width]
