A park near Raphael's home is shaped like a trapezoid. To find its area, Raphael walked along the short base and measured it. Then he walked at a right angle and measured the distance to the other side of the park. Finally he measured the long distance of the base. Use Raphael's measurements shown below to find the area of the park. Enter your answer in the box.

A = h * (a + b) / 2

Step-by-step explanation:

Raphael measured all the measurements necessary to calculate the area of a trapezoid.

First, the short part that we will call "a", then when he walks at a right angle to the other side would be the height, which we will call "h" and lastly he measured the longest side which we will call "b"

The trapezium has as area:

A = h * (a + b) / 2

Therefore, although the problem does not give the values, it is only to replace the values as shown in the previous formula and it can be solved.

i belive those are the ones that are under 90 degreese.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
