Answers:
Area of the trapezoid is 61.6 in^2
Area of triangle is 4.64m^2
Step by step:
The formula for area of a trapezoid is 1/2(b1+b2)*h
So you plug in 12 and 10 as your bases and 5.6 as your height then solve
1/2(12+10)*5.6
1/2(22)*5.6
11*5.6
61.6
For the triangle the formula is 1/2bh
So you plug in 2.9 as your base and 3.2 as your height then solve
1/2(2.9)(3.2).
2.9*1.6
4.64
(Note) it doesn’t matter whether you half the base or the height
Hope this helps!
