b Remember the rule for calculating the area of a rectangle.
A
a 33cm^2
B
b 33xunits^2
Practice makes perfect
a We find the area of a rectangle by multiplying the rectangle's length and width. Examining the diagram, we have been given both of these dimensions and can directly calculate the area.
b In the same way as in the previous problem, we want to multiply the rectangle's length by its width.
