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
