Question

The area of a rectangle with length 21 meters and breadth 31 meters is ____________.​

Answer 1

Step-by-step explanation:

To find Length or Breadth when Area of a Rectangle is given

When we need to find length of a rectangle we need to divide area by breadth.

Length of a rectangle = Area ÷ breadth.

ℓ = A ÷ b.

Similarly, when we need to find breadth of a rectangle we need to divide area by length.

Breadth of a rectangle = Area ÷ length.

Answer 2

Answer:

Area of a rectangle is $651\ m^{2}$ .

Step-by-step explanation:

To find :  area of a rectangle .

Given :  length of rectangle is 21 meters and breadth is 31 meters .

Solution :

• As per given data we know that , length of rectangle is 21 meters and breadth is 31 meters . We have to find area of rectangle .
• To find area we use following formula -
• Area of rectangle $=l \times b$
• Substituting the values we get,

        Area of rectangle = $21\times 31$

                                      $= 651\ m^{2}$
