Answer 2

Given :

• Length of breadth of rectangle = 4:3
• Perimeter of the rectangle = 154 cm

To find :

• The length of the breadth of the rectangle

Solution :

★ Let:-

• Length = 4x
• Breadth = 3x

We know that if we are given the perimeter of a rectangle then we can easily find the length and breadth of the rectangle using this formula:-

• 2(L +B) = Perimeter

★ Here:-

• L = Length
• B = Breadth

★ Substituting the values:-

→ 2(4x + 3x) = 154

→ 2(7x) = 154

→ 14x = 154

→ x = 154/14

→ x = 11

•°• the length of the rectangle = 4x = 44 cm

•°• the breadth of the rectangle = 3x = 33 cm
