Answer:
Area of trapezoid is
.
Therefore, option 2nd is correct.
Step-by-step explanation:
We have been given both the sides a=3 and b=5.
And height that is h=4
We will use the formula find the area of trapezoid is:

Substitute the formula we get:


.
Area of trapezoid is
.
Therefore, option 2nd is correct.
Answer:
yes
Step-by-step explanation:
We find the area of all the faces and add those up
So
Total area = (12*5) + 2(1/2 *3 *4 ) + (4*12)+(3*12)
= 60 + 12 + 48 + 36
= 156 square feet
third option is the correct one
