Answer:
The length of the rectangular park is
and the width of the rectangular park is
Step-by-step explanation:
Let
x ----> the length of the rectangular park
y ---> the width of the rectangular park
we know that
The perimeter is equal to


so
-----> equation A
----> equation B
substitute equation B in equation A and solve for y
Find the value of x

therefore
The length of the rectangular park is
and the width of the rectangular park is
S + a = 722
s = 72 + a
(72 + a) + a = 722
2a + 72 = 722
2a = 722 - 72
2a = 650
a = 650/2
a = 325 <== adults
s = 72 + a
s = 72 + 325
s = 397 <== students
