Answer:
162 in
Step-by-step explanation:
Split this shape into two rectangles:
The big rectangle has a base of 16 and a height of 7 (subtract 12-5=7 for height) Multiply base*height to get area of big rectangle:
16*7 = 112 in
The small rectangle has a base of 10 and a height of 5. Mulitply base*height to get area of small rectangle:
10*5 = 50 in
Add both areas together:
112+50= 162 inches
For this case we have the following functions:
We must subtract the functions:
We build a table of values for
