Pls ✨ , im struggling , show work too pls (i will give out brainliest)

First shape : 204cm^2

Second shape : 57in^2

Step-by-step explanation:

For the first shape :

The front and back triangles are 3 * 8 / 2 which gives us 12 on each side.

The side rectangles are 5 * 10 which is 50 on each side.

The bottom rectangle is 10 * 8 which is 80.

Add them all up and you get 204.

For the second shape :

The triangles are all congruent and the area is 3 * 8 / 2, so we get 12 on each side.

Then the bottom square is 3^2, which is 9.

Add them all up together and you get 57.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
