Question

The length and width of a rectangle are 1.125 m and 0.606 m, respectively. multiplying, your calculator gives the product as 0.68175. rounding properly to the correct number of significant figures, the area should be written as

Answer 1

Area = 0.68 m²

Explanation:

Area of Rectangle = (Length) × (Width)

= 1.125 m × 0.606 m

= 0.68175 m²

Now, For rounding this area following steps are taken:

First, choose the place we want to round off.

Now look the just right digit of that number if it is less than 5 then remove all unwanted digits.

And if the just right digit is greater than 5 then add 1 to the left digit and remove all unwanted digits.

Here if we round off at 2 places then, Area = 0.68 m²

and if we round off at 3 places then, Area = 0.682 m²

Answer 2

Solution: We are given the length of rectangle
`=1.125 m`

width of rectangle
`=0.606 m`

Therefore, the area of rectangle
`= length * width`

`=1.125 m * 0.606 m`

`=0.68175 m^(2)`

`=0.682 m^(2)` rounded to 3 decimal places

Therefore, the area of the rectangle is
`0.682`
`m^(2)`
