Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be [tex]x[/tex] sq ft.

Then the area of kitchen will also be [tex]x[/tex] sq ft.

Let the area of bathroom be [tex]y[/tex] sq ft.

As per question statement:

[tex]x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)[/tex]

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

[tex]2x+2y=980 ..... (2)[/tex]

Subtracting equation (1) from (2):

i.e. (2) - (1):

[tex]y = 140[/tex] sq ft

Putting the value of [tex]y[/tex] in (1):

[tex]2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}[/tex]

Therefore, the carpet needed for each bedroom = 350 sq ft
