Question

(i) You know that area of (RBSESolutions.com) a rectangle = length x breadth. But if length and breadth is given in fraction, then how will you find the area of rectangle?

(ii) Are you agree with that to find the area of a rectangle, we must know how to multiply two or more than fractional numbers?

Solution:

(i) If length and breadth are given in fractional numbers then the numerators are multiplied with numerators and denominators with denominators to find a fraction that is the area of a rectangle:

For example:

length = 4/5 unit and breadth = \(\frac { 3 }{ 7 }\)unit

Then area of rectangle = length x breadth

= \(\frac { 4 }{ 5 }\) x \(\frac { 3 }{ 7 }\) = \(\frac { 4\times 3 }{ 30 }\) = \(\frac { 5 }{ 7 }\)

= \(\frac { 12 }{ 35 }\) sq unit.

(ii) Yes. we are agree with that we must know, how to multiply two or more fractional numbers.

Using a fraction and whole number calculator in situations where you struggle to solve your arithmetic assignments can be useful.
