2100 cm

Step-by-step explanation:

Since a=20 cm, b=25 cm, c=28 cm, we can calculate the area by calculating the separate squares and triangles and then adding them together.

To find the square's areas we can use the equation A=LxW

A=20x25

A=500

Since there are two identical squares add them together.

500+500=1000

Next, calculate the area for the bottom square.

A=25x28

A=700

And then add the two surface areas together.

1000+700=1700

Finally, calculate the area of the two triangles by adding them together to create one square, and then calculating their area.

A=20x20

A=400

Since we know the final surface area we can add them all together to get our answer of 2100 cm.

400+1700=2100

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
