Answer 1

Answer:

1) 36 square units.

2) 190 square units.

Step-by-step explanation:

As you can see, the figures are trapezoids, therefore, you can calculate the area of each one of them with the following formula:

$A=(\frac{B+b}{2})h$

Where:

B is the longer base, b is the shorter base and h is the height.

Then:

1) $B=4units+(8units-2units)=4units+6units=10units\\b=8units\\h=4units$

$A=(\frac{10units+8units}{2})(4units)=36units^{2}$

2) $B=3units+15units+5units=23units\\b=15units\\h=10units$

$A=(\frac{23units+15units}{2})(10units)=190units^{2}$
