Question

a stick, assumed to be 1m long, measured the side of a square field. The area thus calculated was 625 square meter.Later on,it was discovered that the actual length of the stick is 90cm.
Find the actual area of the square field.

Answer 1

Hey,

Area calculated by assumed to be 1 m long stick = 625 m²

=> side supposed to be 25 m or 2500 cm

But every 1 m is actually = 90 cm

=> 25 m = 90 x 25 = 2250 cm

=> side actual length = 2250 cm

=> area = 22.5 m x 22.5 m

=> actual area = 506.25 m²

HOPE IT HELPS:-))
