Step-by-step explanation:
Area of the parallelogram (A) =625sqm
if one side =a m, corresponding height= (h1) =20m
second side = b m,corresponding height = (h2) =25m
1) area of parallelogram = 625 sqm
base * corresponding side = 625
a*h1=625sqm
a*20 =625
a= 625/20
a= 31.5 m
2) A= 625sqm
b*h2=625
b*25=625
b= 625/25
b=25 m
lengths of two sides are a = 31.5m and b= 25m

h²=p²+b²
b²= h²-p²
b²= 25²-20² cm²
b²= 625-400 cm²
b²= 225 cm²
b= √225 cm²
b = 15 cm
AREA OF PARALLELOGRAM =BASE ×HEIGHT
625 cm² = 15cm × HEIGHT
HEIGHT = 625 cm²/15 cm
HEIGHT = 41.6 cm
