To find out the area of the compound figure, divide the figure into 3 rectangles
see the attached figure to better understand the problem
please give me a minute to draw the figure
step 1
Find out the area of rectangle N 1
A=12*3=36 m2
step 2
Find out the area of rectangle N 3
A=15*3=45 m2
step 3
Find out the area of rectangle N 2
A=(12-7)*(12-6)
A=5*6=30 m2
therefore
the total area is
36+45+30=111 m2
the area is 111 square meters
step 4
Find out the perimeter
P=12+12+15+3+10+6+7+3
P=68 m
