A rectangular room has an area of 131/1/4 square feet, the length is 12/1/2 feet, what is the width?
ok
s
hey
ur ugly
To find the width of the rectangular room, we can use the formula for the area of a rectangle: Area = Length × Width. In this case, we are given the area and the length, so we can rearrange the formula to solve for the width.
Let's first simplify the given area. The area is given as 131/1/4 square feet, which can be written as an improper fraction: 131¼ = 525/4 square feet.
Now, we can substitute the given values into the formula:
525/4 = (12/1/2) × Width
To divide by a fraction, we can multiply by its reciprocal. So, we can convert 12/1/2 to an improper fraction and rewrite the equation:
525/4 = 25/2 × Width
To solve for Width, we'll multiply both sides of the equation by the reciprocal of 25/2, which is 2/25:
(525/4) × (2/25) = (25/2) × (2/25) × Width
The 25 in the numerator and the denominator cancel out:
525/4 × 2/25 = Width
To simplify this multiplication, we can simplify the fractions first:
525/4 × 2/25 = (525 × 2)/(4 × 25) = 1050/100 = 10.5
Thus, the width of the rectangular room is 10.5 feet.
A = L * W = 131 1/4 sq. Ft.
12 1/2 * W = 131 1/4,
W = 131.25/12.5 = 10.5 Ft.
