Question

what is the answer tell me step by step​

Answer 1

Answer:

The area of the floor not covered is 38 $m^{2}$.

Step-by-step explanation:

From the figure, we can clearly conclude that,

Area of the floor not covered = Area of the rectangle floor - Area of the squared rug

Case I: The rectangle floor has length = 9 m and width = 7 m.

So, the area of rectangle floor:  

= length x width

= 9 m x 7 m

= 63 $m^{2}$

Case II: The squared rug has length = 5 m.

So, the area of squared rug:  

= $(length)^{2}$

= $(5m)^{2}$

= 25 $m^{2}$

∴ The area of the floor not covered = 63 $m^{2}$ - 25 $m^{2}$

                                                            = 38 $m^{2}$
