measured in square units
1 cm
1 cm
Calculator permitted for 
area problems, but show 
all steps.

2. A= bh
Find the area of each rectangle. Show required steps.
a.) Formula (A=b h)
b.) Substitution (plug in the numbers)
c.) Answer with correct unit • in
6 cm
1.)
2.) in
1.5 cm

3. = A = A parallelogram is just like a rectangle.
6 cm
6 cm =
4 cm
4 cm
therefore the formula is the same.
A =
height
base
