Answer:
2 feet
Step-by-step explanation:
Let 'w' be twice the width of the deck.
The area of the swimming pool is:
The area of the swimming pool plus the deck is:
Therefore, the area of the deck is given by:
Solving the quadratic equation:
Since the width cannot be negative, w = 4 feet, ad the width is 2 feet.
Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=×l
=
hence area of original frame=A=length×width
=
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+×l
=×l
width of new frame==
area of new frame=length×width
=
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%
