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 cm^2. Write the answer to two significant figures.

12cm^2

Step-by-step explanation:

Area of a rectangle = Length × Width

Length = 5.6cm

Width= 2.1cm

Area of the rectangle = Length × Width

= 5.6cm × 2.1cm

= 11.76 centimeter square

Area of the rectangle = 11.76 centimeter square

Answer to two significant figures

There are two figures before the decimal and two figures after the decimal

Since, the question asked us to 2 significant figures, then we will focus on the two figures before the decimal point.

11.76

Using .76 round 11 to the nearest whole number

We have,

12 centimeter square
