Answer:

2,016.67 sq. cm

Step-by-step explanation:

Given the approximate ratio of the sides of a rectangle as 3:4:5.

Total ratio = 3+4+5 = 12

Area of the rectangle = 1/2*base *height

get the base;

base = 3/12 * 220

Base =  55cm

Get the height

Height = 4/12 * 220

Height = 880/12

Height = 73.3cm

Area = 1/2 * 55 * 73.3

Area = 2,016.67 sq. cm
