Answer 1

Answer:

The breadth of a rectangular plot of land if its area is 440 m2 and the length is 22 m is 20 m. Also, its perimeter is 84 m.

Answer 2

Answer:

∴ The breadth of rectangular plot is $20$ cm. and

      Perimeter of a rectangular plot is $88$ cm.

Step-by-step explanation:

In context to question asked,

• We have to find breadth of a rectangular plot and its perimeter.
• The area of rectangular plot = $440$ sq. cm.
• Length = $22$ cm
• The formula for area of rectangular plot is given by,

   Area of rectangular plot = $l*b$  

                           ∴ $440 = 22*b$

                              ∴ $b=\frac{440}{22}$

                              ∴ $b=20$ cm  

• ∴ The breadth of rectangular plot is $20$ cm.
• Now, perimeter of a rectangular plot is the sum of all sides of plot.
• So, formula for perimeter of a rectangular plot is given by,

        Perimeter of a rectangular plot = $2(l+b)$

                                  = $2(22+20)$                  

                                  = $2*44$  

                                  = $88$ cm

   

• ∴ The breadth of rectangular plot is $20$ cm. and

      Perimeter of a rectangular plot is $88$ cm.
