A cement walkway of uniform width has been built around an in-ground rectangular pool. the area of the walkway is 1344 square fe

Elza [17]

Answer:

6 feet.

Step-by-step explanation:

Dimensions of the Pool =80 feet long by 20 feet wide

Area of the walkway =1344 square feet.

If the width of the walkway=w

Length of the Larger Rectangle =80+2w
Width of the Larger Rectangle =20+2w

Area of the Walkway =Area of the Larger Rectangle - Area of the Pool

$1344=(80+2w)(20+2w)-(80*20)\\1344=80*20+160w+40w+4w^2-80*20\\4w^2+200w=1344\\4w^2+200w-1344=0\\We factorize\\4(w^2+50w-336)=0\\4(w^2-6w+56w-336)=0\\w(w-6)+56(w-6)=0\\(w-6)(w+56)=0\\w-6=0$ or $ w+56=0\\w=6$ ft or $ w=-56$ \\Therefore, the width of the walkway , w=6 feet.$

3. A carpenter is framing a window with wood trim where the length of the window is 6 and 2\3 feet. If the width of the window i

wel

We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.

SO the length of rectangular window is $= 6 \frac{2}{3} = \frac{20}{3}$ feet.

Width of the rectangular window is = $7 \frac{3}{4} = \frac{31}{4}$ feet.

In general parameter of rectangle is = $2(l+b)$

So the parameter of window is = $2( \frac{20}{3} + \frac{31}{4}) = 2* \frac{(80+ 93)}{12} = 2* \frac{173}{12} = 28.834$

So the required length of wood to frame window is = 28.834 feet
