Answer 1

Natalie,

 

Length of rug is 38.4 inches

Width is 24.2 inches

 

1 inch = 2.54 cm

 

So length in cm is 38.4*2.54 = 97.536 cm

Width in cm = 24.2*2.54 = 61.468 cm

 

There are 3 significant figures in length measurement

 

Area of rug = 97.536*61.468 = 5995.342848 sq cm

For 3 significant digits the area is 5995.343 sq cm
