Your bedroom has a rectangular shape and you want to measure its size. You use a

This question is in two parts. This is not the correct multiple choice options for this part a.

The second part had the option

b)If your bedroom has a circular shape, and its diameter measured 6.32 , which of the following numbers would be the most precise value for its area?

a)30 m^2

b) 31.4 m^2

c)31.37 m^2

d)31.371 m^2

A. 17.0 m²

B. 31.4 m²

Explanation:

The formula for the calculation of the area of a rectangle is given as

Area = length x width

The length = 3.547 m

The width = 4.79 m

Then area = 3.547 x 4.79

= 16.990m²

When approximated = 17.0m²

This is the most precise measurement for the area of the bedroom.

B.

We solve b using this formula

Area = pi(diameter/2)^2

= 3.14(6.32/2)²

= 3.14 x 9.9856

= 31.4 m²

actually dont listen to him the correct answer is b. meandering on mommas .
