Answer:
99 square ft
Step-by-step explanation:
Area of the composite shape
= Area of rectangle - Area of triangle
[tex] = 12 \times 10 - \frac{1}{2} \times 6 \times 7 \\ \\ = 120 - 21 \\ \\ = 99 \: {ft}^{2} [/tex]
99 square feet
Simply solve for the rectangle using a=lw
12 x 10 = 120
Now subtract the area of the triangle using a=bh/2
7 x 6= 42
42/2= 21
120-21= 99
Hope this helps.
