The fence is rectangular, so use the formula for the area of a rectangle: .

You know the area (A = 300 ft2) and the width (w = 4 ft), but not the length. The formula would be more useful if it were rewritten to solve for the length in terms of the area and width. Rewrite the formula by dividing both sides by the width.


Use the formula to find the length of fence (in feet) that can be painted.

Answer: New formula is A/w=l

Length equals 75ft.

Step-by-step explanation:

A=l x w           Area of a rectangle formula.

A/w=l              Solve for length

300=l x 4      

300=l x 4

4           4

300/4=l

75=l

The new formula is A/w=l and  Length= 75ft.

A=l x w        (Area of a rectangle formula)

A/w=l           (Solve for length)

300=l x 4      

300=l x 4

300/4=l

75=l

What's the vicinity system?

Given a rectangle with duration l and width w, the system for the location is A = lw (rectangle). that is, the place of the rectangle is the duration accelerated by the width. As a unique case, as l = w inside the case of a rectangular, the location of a rectangular with facet duration s is given with the aid of the formulation: A = s2 (rectangular)

The perimeter P of a rectangle is given through the formulation, P=2l+2w, wherein l is the period and w is the width of the rectangle. The location A of a rectangle is given with the aid of the system, A=lw, where l is the length and w is the width.
