Question

A carpet is to be installed in a room of length 8.71 m and width 6.2 m. Find the area of the room retaining the proper number of significant figures.

Answer 1

Answer:

54.0 m²

Explanation:

The area of any rectangular object can be calculated by the formula,

$A=L\times W$

Here, L is the length, W is the width and A is the area.

According to question, the length of the carpet is 8.71 m and the width of the carpet is 6.2 m.

Therefore area of the carpet is,

$A=8.71 m\times 6.2 m\\A=54.002 m^{2} \simeq54.0m^{2}$

Therefore the area of the carpet upto proper significant digit is 54.0 m².
