Question

How many square meters of carpet will be required for a square room of side 7.2 m. to be carpeted? Apply distributive law to find the square of a decimal​

Answer 1

Step-by-step explanation:

SOLUTION :

Given,

dimensions of the rectangle are 6.4m and 2.5m

Area of the rectangle = length × breadth

Area of the rectangle = 6.4 × 2.5 = 16m²

Let the side of square be 'y' m

According to the question,

Area of square = Area of rectangle

\begin{lgathered}= > {y}^{2} = 16 \\ \\ = > y = \sqrt{16} \\ \\ \therefore y = 4m \\ \\\end{lgathered}

=>y

2

=16

=>y=

16

∴y=4m

Hence, the side of the square is 4m.
