Answer:
1. Equation:
That means (6×4)÷2
=24÷2
=(12)
Next we multiply by three since it saud three triangles
=12×3
=(36)
So the answer is 36 square inches
2. Equations:
That means (3×5)÷2
=15÷2
=7.5
Then multiply by 2
=7.5 × 2
=(15)
On rectangle 4×3
=(12)
Now put the two together
15+12=27
The answer is 27 square inches
3. Equations:
On the rectangle
12×16= (192)
For the circle
(since the given is diameter divide the diameter by half to get readius)
=12÷2
=6
Then multiply π and the radius and the radius
(π = 3.14)
=3.14 × 6 × 6
=3.14 × 36
=113.04
Now since the figure shows half the circle divide the answer you got by 2
=113.04 ÷ 2
=(56.52)
Now after you get both off the area add them both
=192+56.52
=248.52
The answer is 248.52 square feet
