Question

Is it possible to design a rectangular park of perimeter 80 m and area 400 m²? If so, find its length and breadth.

Answer 1

Answer:

yes, it's possible only when the park is a square(special rectangle)

having each side of 20 m

perimeter = 2(l+b)

=2(20+20) = 2(40) = 80 m

area = l x b

= 20 x 20 = 400 m

hence proved...
