Answer:
Area of rectangle = l*b
61.2 = 7.2*l
l = 8.5m
Perimeter = 2(l + b)
= 2(8.5 + 7.2)
31.4m

Given
- Length of rectangle ⇒ 12 m
- Area of rectangle ⇒ 60 m²
_______________________________
To Find
- Breadth of rectangle
- Perimeter of Rectangle
_______________________________
Solution
Area of Rectangle ⇒ Length × Breadth
Length ⇒ 12 m
Breadth ⇒ x m
Breadth ⇒ Area ÷ Length
Breadth ⇒ 60 ÷ 12
Breadth ⇒ 5
∴ Breadth = 5 m
Perimeter of Rectangle ⇒ 2 (Length + Breadth)
Length ⇒ 12 m
Breadth ⇒ 5 m
Perimeter of Rectangle ⇒ 2 (12 + 5)
Perimeter of Rectangle ⇒ 2 (17)
Perimeter of Rectangle ⇒ 34
∴ Perimeter of Rectangle = 34 m
