Area of a triangle is half multiplied by the height multiplied by the base.So multiplying the two together and halfing is shown below
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
<span>The answer is She should have multiplied by 2 instead of dividing by 2.
First one.</span>
