How do you find the base area of a rectangular prism and a cylinder? Please help
Pani-rosa [81]

Answer:

See explanation.

Step-by-step explanation:

The 'base' of a rectangular prism refers to only one side of the rectangular prism, which is a rectangle.

The formula for the area of a rectangle is as follows:

A=lw

Where A = area, l = length, and w = width.

The 'base' of a cylinder refers to only one side of the cylinder, which is a circle.

The formula for the area of a circle is as follows:

A=\pi r^2

Where A = area and r = radius.

Just in case you typed your question incorrectly and were asking for surface area, here is the formula for surface area for both as well:

Rectangular prism: A=2(wl+hl+hw)\\

Cylinder: A=2\pi rh+2\pi r^{2}
