Question

Help my please I don't know how to do it due for tomorrow night

Answer 1

For trapezoids, the area is:

(B1+B2) x H
-------------------
2

B1 = one of the two sides that are parallel to each other

B2 = the other of the two parallel sides that are equal to each other

H = the height of the shape

So for problem 1, it would look like:

(7+9) x 5
-------------
2

And that would end up being 40 cm^2

For problem 2, it's

(5.7+4.7) x 3.2
--------------------
2

And for problem 3, it's

(5.8+7.4) x 3.9
---------------------
2


Hope that helps!
