12.) yolanda walked 3 6710 mins then she walked 45
more miles. how many total miles did yolanda wak?

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.
