Answer: <u><em>Problem 1</em></u>
SA = 430.0
Step-by-step explanation:
13*11=143 divided by 2 is 71.5 (front face of the figure)
13*11=143 divided by 2 is 71.5 (backk face of the figure)
13*7=91 (left side rectangle)
17*7=119 (right side face rectangle)
11*7=77 (base)
Add all together 71.5+71.5+91+119+77=430.0
<u><em>Problem 2</em></u>
10*9=90 divided by 2 = 45 (front face triangle)
10*9=90 divided by 2 = 45 (back face triangle)
10*9=90 (right side rectangle face)
10*13.5=135 (left back side rectangle face)
10*10=100 (base)
Add everything together
45+45+90+135+100=415.0
Hope this helps!
