Question

the length and breadth of a rectangle are 6 metre and 120 CM respectively find its area in sq. Metre​

Answer 1

Answer:

l=6m=600cm

b=120 cm

area of rectangle = l×b

= 600×120

=720000 cm 2

= 720000÷100×100

=72 m2

Answer 2

Given : The length and breadth of a rectangle are 6 metre and 120 cm respectively.

To find : The area of the given rectangle in sq. metres.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the area of the given rectangle in sq. metre unit)

Now,

• Length of the rectangle = 6 m
• Breadth of the rectangle = 120 cm = (120 ÷ 100)m = 1.2 m [As, 1 m = 100 cm]

(We have converted the unit of the breadth from centimetre to metre, because we need the area in square metre. For the area being in square metre unit, both the length and the breadth are preferable in metre unit.)

So, the area of the given rectangle will be :

= Length × Breadth

= (6 × 1.2) m²

= 7.2 m²

(This will be considered as the final result.)

Hence, the area of the rectangle is 7.2 m².
