Q4 of 97 Page 780

The area of a rectangular plot is 462 m2 and its length is 28 m. Find its perimeter.

Given: Area = 462 m2


Length = 28 m



We know that,


Area of rectangle = Length × Breadth


⇒ 462 m2 = 28 m × Breadth



⇒ Breadth = 16.5 m


Now,


Perimeter of a rectangle = 2(length + breadth)


= 2(28 m + 16.5 m)


= 2 × 44.5 m


= 89 m
