Answer
a) Separate into squares with 3 cm sides.
b) $64 ft^2$
Work Step by Step
a) The figure could be divided into 6 squares with 3 cm sides. Compute the area of one square and multiply by 6 to find the total area of the figure.
b) Divide the figure into one rectangle that has a 12 ft base and a 4 ft height and a triangle that has an 8 ft base and a 4 ft height. Find the area of each and add them to find the area of the figure.
$A_1=bh=12\times4=48$
$A_2=\frac{1}{2}bh=\frac{1}{2}(8)(4)=(4)(4)=16$
$A=A_1+A_2=48+16=64$
