First cut the figure 3 pieces
To find the smaller rectangle multiply 7 by 4 and get 28
Then multiply 18 by 7 and get 126
Then find the area of the quarter of a circle to find that first fine the area of the circle if it was whole, the formula is A=pi r^2 when you put the numbers into that you get 28.27433. Then divide that by 4 to get the area of the quarter circle which is 7.0685825
Last add all of the answers together.

28+126+7.0685825= 161.068525

Starting with the quarter of a circle
The area of the circle is pi r^2
Area = 113.04 but the quarter of the circle =113.04 / 4= 28.26

Now for the first rectangle,
The area is Lxw
(11+3) x(4) = 56

For the second rectangle,
The area is 14x7 =98

The total area will be 98+56+28.26
= 182.26
