The length of the rectangular section is 120 m, the width is 46 m. Find the width of another rectangular section with the same area, the length of which is 80 m.
The length of one section is 120 meters.
The width of the 1st section is 46 meters.
Area – ? m².
The length of the second section is 80 meters.
Width of 2 sections -? meters.
The area of the 2nd plot is equal to the area of the 1st plot.
We find the area of the rectangle by the formula:
S = a * b.
S = 120 * 46.
S = 5520 m² – 1 plot.
The area of the 2nd plot is also 5520 m².
5520 = 80 * b,
b = 5520: 80,
b = 69 meters width of 2 sections.
Answer: 69 meters width of the second section.
