Question

How do you find the area of a rectangle that is 7.5 cm long and 4 cm wide?

Answer 1

`30` sq. cm.

Explanation:

Formula for area of a rectangle is `A = lxxw`
`color(white)("XXX")`where `A` is the area, `l` is the length, and `w` is the width

`A= 7.5 " cm" xx 4 "cm"`
`color(white)("X")=30 " cm"^2`
