Question

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

Solution

Area = Length × Breadth = 440 m2

22 × Breadth = 440

Breadth =`440/22`= 20 m

Perimeter = 2 (Length + Breadth)

= 2 (22 + 20) = 2 (42) = 84 m2

  Is there an error in this question or solution?
