Question

The area of a rectangular field is 61.2 square metres. If the breadth of the rectangle is 7.2 m find the perimeter of the rectangle

Answer 1

Step-by-step explanation:

Finding the length :

=> Area = l × b

=> 61.2 = l × 7.2

=> 61.2/7.2 = l

=> 8.5 = l

$\bf{lenght \: is \: 8.5 \: m}$

=> Perimeter =2(l + b)

=> Perimeter = 2(7.2 + 8.5)

=> Perimeter = 2(15.7)

=> Perimeter = 2 × 15.7

=> Perimeter = 31.4
