Answer:
12
Step-by-step explanation:
Given, perimeter of square is equal to perimeter of rectangle
2(l+b) = 64
l+b = 64/2
20+b = 32
b = 32-20
b = 12

Answer:
240 cm^2
Step-by-step explanation:
given,
perimeter of the square park = 64 cm
length of the rectangular park = 20cm
and even given indirectly that,
perimeter of the rectangular park = 64 cm
we know that,
perimeter of rectangle = 2(l+b)
= 2(20+b) = 64
=40+2b = 64
= 2b = 64-40
= 2b= 24
= b= 12 cm
so now,
area of the rectangle = l*b
= 20*12
= 240 cm^2
