Question

each side of a square is 45cm and a rectangle has length 50cm.if the perimeter of both (square and rectangle)are same,find the breadth of the rectangle​

Answer 1

Answer :

• Breadth of rectangle is 40cm

Given :

• Each side of a square is 45cm
• Length of rectangle is 50cm
• Perimeter of both square and rectangle are same

To find :

• Breadth of rectangle

Solution :

Given

• Side of square is 45cm

We know that,

• Perimeter of square = 4a

》Perimeter of square = 4a

》Perimeter of square = 4 × 45

》Perimeter of square = 180 cm

Given, The perimeter of both (square and rectangle)are same then,

• Perimeter of rectangle is 180cm

Finding the breadth of rectangle :

Given

• Length of rectangle is 50cm
• Perimeter of rectangle is 180cm

• Let the breadth of rectangle be b

We know that,

• Perimeter of rectangle = 2(l + b)

where,

• l is length of rectangle
• b is breadth of rectangle

》Perimeter of rectangle = 2(l + b)

》180 = 2(50 + b)

》50 + b = 180/2

》50 + b = 90

》b = 90 - 50

》b = 40cm

Hence, Breadth of rectangle is 40cm
