An equation is formed of two equal expressions. The width of the rectangle is 44 units.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the length of a rectangle is 4 units shorter than half the width. Therefore, we can write the equation as,
L = (w/2)-4
Now, since the length of the rectangle is 18 units, therefore, the width can be found as,
18 = (w/2)-4
18+4 = w/2
22 = w/2
w = 22×2
w = 44
Hence, the width of the rectangle is 44 units.
