Answer:

The area of the larger rectangle is 40.32 cm²

Step-by-step explanation:

Two rectangles are similar if the lengths of their corresponding sides form a proportion. From the picture:

4.8/4 = x/7

where x is the length of the base of the larger rectangle.

x = (4.8/4)*7

x = 8.4 cm

The area of the larger rectangle is:

A = base*height

A = 8.4*4.8

A = 40.32 cm²
