A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom

Dennis_Churaev [7]

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 $x$ sq ft.

Then the area of kitchen will also be $x$ sq ft.

Let the area of bathroom be $y$ sq ft.

As per question statement:

$x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)$

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

i.e.

$2x+2y=980 ..... (2)$

Subtracting equation (1) from (2):

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

$y = 140$ sq ft

Putting the value of $y$ in (1):

$2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}$

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>

Step-by-step explanation:

we know that

The area of the decking is equal to the area of the parallelogram minus the area of the pool minus the area of the sand box

Remember that

$21\frac{1}{2}\ ft=21.5\ ft$

$A=(50)(35)-(20)(25)-(21.5)(7)/2\\A= 1,750-500-75.25\\A=1,174.8\ ft^{2}$
