width of rectangular park= 49 cm
let the length of rectangular park be x
it is also given that,
area of square park =area of rectangular park
side ×side =length×width
70×70 = x×49
70×70
------------ = x
49
100 = x


to find perimeter of rectangular park
perimeter of rectangular park = 2 (l +b)
= 2 (100 + 49)
=2× 149
