Question

B1=5,b2=7,h=4 need help plz

Answer 1

Answer:

$A=24$

Step-by-step explanation:

For finding the area of a trapezoid you first have to use the correct formula which is  $A=\frac{1}{2}(b_1+b_2)h$.

Now we plug in what we already know.

$A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)$

Now we start with the parenthesis

$A=\frac{1}{2}(12)(4)$

Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally

$A=24$
