write an expression for the area of this rectangle 20cm on the top 4cm on the right at the top and 8cm on the left.evaluate your expression to find the area.
A= l*W*H
20*4*8= 640

Area is two dimensional, while volume is three dimensional. Otherwise, stephani is correct, but the equation should be:
Volume = Length * Width * Height
I hope this helps a little more. Thanks for asking.
i need help surface area of the cyliner whose radius is 2.8m and height is 5.8m

To find the area of a rectangle, we multiply its length by its width. In this case, the length is 20 cm (top side) and the width is the sum of the two sides on the right and left, which is 4 cm + 8 cm = 12 cm.
So, the expression for the area of this rectangle is:
Area = Length × Width
Area = 20 cm × 12 cm
Now, let's evaluate the expression to find the area:
Area = 240 cm²
Therefore, the area of the given rectangle is 240 square centimeters.
