Question

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm2. Now suppose you are asked to enter the answer to two significant figures. (Note that if you do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.) Enter your answer to two significant figures and include the appropriate units. nothing nothing

Answer 1

`12 cm^2`

Explanation:

We are given that

Width of rectangle=b=2.1 cm

Length of rectangle=l=5.6 cm

We have to find the area of rectangle.

We know that

Area of rectangle=
`l* b`

Using the formula

Area of rectangle =
`2.1* 5.6`

Area of rectangle=
`11.76\approx 12 cm^2`

Hence, the area of rectangle=
`12 cm^2`
