Answer:
340 square feet
Step-by-step explanation:
If we "unwrap" the painted surface from the shed, it will have the shape shown in the attachment. It is essentially a 40' by 8' rectangle with two 10' wide by 2' high triangles added.
The rectangle area is ...
A = LW = (40 ft)(8 ft) = 320 ft²
The total area of the two triangles is ...
A = 2(1/2)bh = (10 ft)(2 ft) = 20 ft²
Then the painted area is ...
total area = 320 ft² +20 ft²
total area = 340 ft²
Well the formula for the area of a trapezoid is as follows:
A=
where a and b are both base measures (a trapezoid has a top and bottom base).
Therefore, if all three have the same base length (the top and bottom lengths themselves being different yet the same on all three), the trapezoid with the greatest angle measure would have the greatest are. This is because with a greater angle measure comes a greater height (Pythagorean theorem).<span />
