Answer:
Area[tex]=70in^2[/tex]
Step-by-step explanation:
The given diagram is a tra-pezoid.
The area of a tra-pezoid is calculated using the formula;
Area[tex]=\frac{1}{2} (Sum\:of\:parallel\:sides)\times height[/tex]
This implies that;
Area[tex]=\frac{1}{2} (8+12)\times 7[/tex]
Area[tex]=\frac{1}{2} (20)\times 7[/tex]
Area[tex]=(10)\times 7[/tex]
Area[tex]=70in^2[/tex]
The last choice is correct.
