What is the area of the smaller rectangle

Step-by-step explanation:

The formula of an area of the smaller rectangle:

A = xy

The formula of an area of the larger rectangle:

A' = (3x)(3y)=9(xy) = 9A

We have the area of the smaller rectangle:

A = 420 in²

Therefore the area of the larger rectangle is:

A' = 9(420) = 3780 in²
