Could you please answer quickly?!! thank you!

31,5

Step-by-step explanation:

=7*3+(7*3)/2

length x width = area

7 x 3 = 21 so the area of the rectangle is 21

divide 7 by 2 so we can find the length of each triangle. 7 / 2 = 3.5

length (or base) x height / 2 = area of triangle

3.5 x 3 = 10.5

You do not have to divide by two because there are two triangles

10.5 + 21 = 31.5 so the area is 31.5

Hope this helps

Step-by-step explanation:

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
