Question

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

Pro Projukta · Accepted Answer

Area is 625
so side of square is 6251/2
which is equal to 25m
but the length of the stick was not 1m but 0 9m so
side =0 9*25 =22 5m
Actual area = 22 52
i e 506 25 sqm

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