Question

For each expression determine whether it gives the perimeter of the rectangle the area of the rectangle or neither.

Answer 1

The area of a rectangle with dimensions "a" by "b" is given by the following:

`area=a\cdot b`

While the perimeter is given by:

`perimeter=2\cdot a+2\cdot b`

With this in mind we can see that:

"A" represents the area.

"B" represents neither.

"C" represents neither.

"D" represents the perimeter.
