Question

The length of a rectangle is four meters less than twice its width.

If the area of the rectangle is 96 m^2, what is the length and the width?

An expression for the length of the rectangle in terms of the width would be__________

The formula for the area of a rectangle is _________

Using trial and error, if the area is 96 m^2, then the length and width are-________

word bank:
:: 1 = 4-2w
:: l = 12 & w=8
:: l = 24 & w = 4
:: 1=8&w=12 area = // (1 xw)
:: area = 21 + 2w =lxwarea=
:: 1=2w-4 ::w=21-4
:: 1 =4&w= 24

Answer 1

An expression for the length of the rectangle in terms of the width would be: l = 2w - 4

The formula for the area of a rectangle is: Area = length x width

Using trial and error, if the area is 96 m^2, then the length and width are:
l = 12 & w = 8 (length = 12 meters, width = 8 meters)
or
l = 24 & w = 4 (length = 24 meters, width = 4 meters)
