Of the two square fields, the area of one is 1 hectare while the other one is broader by 1%. The difference in their areas is :
Answer & Solution
Correct Answer:
Option
D
Area = 1 hect. = 10000 sq. m
Side = $$\sqrt {10000} $$ m = 100 m
Side of the other square = 101 m
Difference in their areas :
= [(101)2 - (100)2] m2
= [(101 + 100) (101 - 100)] m2
= 201 m2
Side = $$\sqrt {10000} $$ m = 100 m
Side of the other square = 101 m
Difference in their areas :
= [(101)2 - (100)2] m2
= [(101 + 100) (101 - 100)] m2
= 201 m2
