So this is a two step process, first you must find the area of the rectangle, then find the area of the semicircle.
So to find the area of a rectangle, you use: Length*Height=Area
In this case that would be: 7*2=14cm
Next you find the area of the semicircle, to do this you first find the area of the circle (Pi*r^2) then divide it by 2.
The diameter of the circle is 4 because: 7-2-1=4cm
Next divide that by 2 so that you get the radius: 4/2=2cm
Not you can plug that into the equation to get the area of the circle: Pi*2^2<span>≈13cm^2
Next divide it by 2 so that you get the area of the semicircle:13/2</span><span><span>≈</span>6cm^2
At this point you can add the area of the semicircle to the area of the rectangle: 14+6=20cm^2
So your final answer is 20cm^2!

Heres the answer hope this helps! :)
4 and 15. You can guess and check or use algebra.
Answer:
B) Going to the close store is cheaper.
Step-by-step explanation:
Cost of going to the next town:
(8.3mi/22mi) × $3.79 = $1.43
Cost of going to the close store:
(2.3mi/22mi) × $3.79 = $0.40
