Question

What is the area of a rectangle with a length of 12cm and a width of 15cm?

Answer 1

`A=180" cm"`

Explanation:

The formula for the area of a triangle is its length, l, multiplied by its width, w:
`"where "A="area", l="length", w="width"`
`A=l*w`

To begin, we know the length of our rectangle is 12 cm:
`l=12" cm"`

We also know the width of our rectangle is 15 cm:
`w=15" cm"`

Substitute them into the formula for area of a rectangle (`A=lw`).
`A=12*15`

Then, calculate our answer.
`A=180" cm"`

`:.` The area of the rectangle is 180 cm.
