Answer:

Step-by-step explanation:
In order to find the area of a square you take the base and multiply it by the height.
Base x Height = Area
In this case you have 7cm as the base and 6cm as the height.
All you have to do after that is multiply the two together.
Make sure that you remember to put the unit (cm) and make sure that it is
because some teachers are uptight about that stuff.
Hope this helped!

Answer:
Step-by-step explanation:
Ok so the formula for a circle is
A=πr2
The diameter of the semicircle is 15, so if you divide that by 2 you will get a radius of 7.5. Then, the next part of the formula is to square the radius, and to do that you need to multiply the radius by itself. You will then get an answer of 56.25. And then finally, you multiply 56.25 by pi, which is 3.14 and get 176.625. Then for the quarter circle, you have 2 side lengths of 15 feet. To find the area of the quarter circle, do pi times the radius(15), and square the answer. Then, divide the answer by 4 to get the quotient, 554.6025. 176.25 + 554.6025 is 730.8525
. That rounded to the nearest 100th is 730.85.
I really hope this helped and I'm sorry if it is incorrect.
