Problema Solution

A rectangular park is 130 yards long and 100 yards wide.

Give the length and width of another rectangular park that has the same perimeter but a smaller area

Answer provided by our tutors

the perimeter of the first park is:


P1 = 2(130 + 100)


P1 = 460 yd


the area of the first park is:


A1 = 130*100


A1 = 13,000 yd^2


Example for another rectangular park that has the same perimeter but a smaller area:


w = 30 yd width


l = (1/2)(460 - 2*30)


l = 100 yd length


the area of this park is:


A2 = l*w


A2 = 100*30


A2 = 3,000 yd^2 smaller than 13,000 yd^2, the area of the first park.
