Question

What is the area in square millimeters of a rectangle with a width of 8.7 centimeters, and a length of 9.3 centimeters? A. 8091 mm2 B. 80,910 mm2 C. 809.1 mm2 D. 80.91 mm2

Answer 1

For any rectangle, the area is equal to the length times the width.

`A=wl`

Here, our width is 8.7 cm and our length is 9.3 cm.
We want an answer in mm, so let's convert to mm.
1 cm = 10 mm, so
8.7 cm = 87 mm and
9.3 cm = 93 mm

Now we multiply 87 by 93 to get our area.
