Question

Please helppppp!!!!!!!!

Answer 1

Answer:

A=128 cm²

Step-by-step explanation:

Hi there!

We are given a trapezoid and we want to find the area of it

The area of a trapezoid is given as $\frac{a+b}{2}h$, where a and b are the bases and h is the height

The bases are the parallel sides

They are the sides marked as 10 cm and 22 cm in this case

The height is the distance between the bases

In this case, it is the side marked as 8 cm

We know everything needed for the area, let's just label everything to avoid any confusion

a=10

b=22

h=8

Now substitute into the formula

A=$\frac{a+b}{2}h$

A=$\frac{10+22}{2}*8$

add the numbers on the numerator together

A=$\frac{32}{2}*8$

Divide 32 by 2

A=16*8

multiply

A=128 cm²

Hope this helps!

Answer 2

Answer:

128 cm^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

where b1 and b2 are the lengths of the bases and h is the height

A =1/2( 10+22) * 8

A = 1/2 (32)8

  = 128
