Answer 1

areA of rectangle:- l*b

192:- x*3x

192= 4x

x- 192/4

x:- 48

breadth:- 48

lenght:- 48*3

Answer 2

Given:

• The length of a rectangular field is three times its breadth. If the area of the rectangle is 192 cm²

To Find:

• Length and breadth

Solution:

• Let the breadth = x cm
• Length = 3x cm

Area of Rectangle = L × B

Where,

• L = Length
• B = Breadth

➠ 192 = x × 3x

➠ 192 = 3x²

➠ 192/3 = x²

➠ 64 = x²

➠ x = 8cm

Hence,

• Breadth of rectangle = 8 cm
• Length of Rectangle = 3 × 8 = 24 cm
