Step-by-step explanation:
Area = h*(b1+b2)/2
well b1 is 4 and b2 is 8 because 4+4
to find h you need to know pythagorean theorem which is a^2+b^2=c^2
well c is always the longest measurement and directly across from the right angle so in this case it is 5. a is just the base which is for so you can just plug that into a calculator to get b as 3.
b is your height so now you have everything you need to know in order to get the answer
h = 3
b1 = 4
b2 = 8
