Answer:
A =222 in^2
Step-by-step explanation:
A trapezoid has an area given by
A =1/2 (b1+b2) h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2( 21+16) *12
A = 1/2 (37) 12
A =222 in^2
Joey is selling fruits for a fundraiser. He’s selling grapes, apples, and pears. At the end of the day he sold 97 fruit. If he sold 40 apples and 17 pears, How many grapes did he sell?

27/3=9 so that’s the simplest form
The mass of a thin triangular plate bounded by the coordinate axes is 3 3/4.
<h3>How to calculate the mass?</h3>
It should be noted that mass simply means a quantity of matter that's in a body. It's the meaure of the inertia in the body.
In this case, from the complete question, the mass will be:
= 3/1000[1/24x⁴ - 25x² + 1000/3x]
= 15/4
= 3 3/4
