The breadth of a rectangular floor is 3/5 of its length. If the area of the floor is 60 metre , then what is the difference between the length and breadth of the floor?
Answer & explanation
Correct answer: option 4
We know that,
Area of the rectangle = length × breadth
We have,
The breadth of a rectangular floor = \(\frac{3}{5}\) of its length.
Area of the floor of rectangular hall = 60 m2
Let length of hall = 5a
Breadth of hall = 5a × \(\frac{3}{5}\) = 3a
According to the question
3a × 5a = 60
= 15a2 = 60
= a2 = 4
a = 2
Difference between length and breadth = 5a – 3a = 2a = 4 m
