Answer:
145,7
Step-by-step explanation:
The area of the circle is 2πr
The area of the rectangle is b·h
Applied to this figure is:
2·π·r = 2·3,14·5 = 31,4 this is a semicircle so you have to divide by 2. 31,4/2 = 15,7
b·h = 13·10 = 130 (you can know the high because the double of the radio is the diameter)
130 + 15,7 = 145,7
