A rectangular park is 50 meters wide and 90 meters long. Give the length and width of another rectangular park that has the same
larisa [96]

Answer:

l = 100\,m and w = 40\,m

Step-by-step explanation:

The formulas for the area and perimeter of a rectangle are, respectively:

A = w\cdot l

p = 2\cdot (w + l)

The perimeter is equal to:

p = 2\cdot (50\,m + 90\,m)

p = 280\,m

Area is likewise equal to:

A = (50\,m)\cdot (90\,m)

A = 4500\,m^{2}

Then, equations are now described:

A = w \cdot l

140\,m = w + l

Likewise, the equation of area is simplified afterwards:

A = (140\,m - l)\cdot l

A = 140\cdot l - l^{2}

The area is reduced inasmuch as length is increased. Let assume that length is 100 meters. The length and width are described herein:

l = 100\,m and w = 40\,m
