b) what are of the floors that is not covered by the carpet?​

Answer 1

Answer:

ans (b). area of rect. (lxb)=7x4=28m²

area of. sqare (s)² =2x2=4m².

area that not cover by carpet=(area of rect)-(area of square)

(28)m²-(4)m²

=24m²

Answer 2

Answer:

a) 7

b) 0 m

Step-by-step explanation:

First, find the area of the living room.

Formula - length × breadth

= 7 m × 4 m = 28 sq.m

Now, find the area of a single carpet.

Formula - side × side

= 2 m × 2 m = 4 sq.m

Number of carpets = $\frac{area \: of \: room}{area \: of \: single \: carpet}$

= $\frac{28}{4}$

= 7 carpets.
