3 triangles area= 12+12+12= 12(3)=36sq.in
2. Area triangle = 0.5(bh)

2A=2(7.5)=15sq.in
A of Rect = l × w
A=4(3)= 12sq.in
total Area= 2A triangle + A rect
A total = 15+12 = 27sq.in
3. A rect = l×w = 16(12) = 192 sq.ft
A semi circle = 0.5(π)(r)(r) = 0.5π(6)(6)= 18π
A total = 27 + 18π = 83.5487 sq.ft
