Do 4 1/4 - 1/4 which is easy, just take away the 1/4 and you get 4, so he used 1/4 gallons
Answer:
<h3>Length = 30 feet </h3><h3>Width = 21 feet </h3>
<em><u>Given </u></em><em><u>-</u></em><em><u> </u></em>Length is nine feet more
Area is 252
<u>To </u><u>find </u><u>-</u><u> </u><u> </u>Value of length and width
<em><u>Solution</u></em><em><u>-</u></em><em><u> </u></em>
let the width of the carpet be X
therefore length = 9 + X
Area of carpet = Length * width
252 = (9+x) * X
252 = 9x + x²
<em><u>Solving </u></em><em><u>the </u></em><em><u>equation </u></em><em><u>by </u></em><em><u>splitting </u></em><em><u>middle </u></em><em><u>term </u></em>
x² + 9x - 252 = 0
x²- 21x + 12x - 252= 0
x ( x - 21) + 12( x - 21) = 0
(x -21)( x + 12) = 0
X = 21 or X = (-12)
Length = 9 + X
= 30 or (-3)
negative is not possible so
length = 30
width = 21
