Alrighty
we gots 1/4 circle and paralellogram
area circle=pi times radius^2
area paralelogram=base times height
1/4 circle is 
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²
area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30
30+78.5=108.5 m² is the area

Answer:
15=13
Step-by-step explanation:
15=-6 you solve the left side, 7+6 which is 15?
15=-6 = 
7+6 = 13
15=13
i'm not sure...
