Question

33. A rectangle and a square have the same perimeter 100 cm. Find the side of the square.Find the side of the square. If the rectangle has a breadth 2cm less than that of the square. Find the breadth, length and area of the rectangle.
​

Answer 1

Answer:

The perimeter of rectangle = 2(l + b). Perimeter and Area of the Square: Perimeter of square = 4 × S. Area of square = S × S.

Answer 2

❥ Given Data :

• Perimeter of Rectangle = 100 m
• Perimeter of Square = 100 m
• Rectangle has a breadth 2 m less than that  of the Square

❥ To Find :

• Side of the Square
• Length of the Rectangle
• Area of the Rectangle

❥ Answer :

• Length of Rectangle = 27 m
• Area of Rectangle = 621 m²

❥ Step by Step Explanation :

Perimeter of Rectangle = Perimeter of Square = 100 m

✿ First Let's Find Side of Square

➸ Perimeter of Square = 100 m

➸ 4 × Side = 100 m

➸ Side of Square = 25 m

✿ Now Let's Find Breadth of Rectangle

➸ Breadth of Rectangle = Side of Square - 2 m

➸ Breadth of Rectangle = 25 m - 2 m

➸ Breadth of Rectangle = 23 m

✿ Now Let's Find Length of Rectangle

➸ Perimeter of Rectangle = 2 × (Length + Breadth)

➸ 100 m = 2 × (Length + Breadth)

➸ 100 m = 2 × (Length + 23 m)

➸ 100 m = 2 × (Length) + 46 m

➸ 100 m - 46 m = 2 × (Length)

➸ 54 m = 2 × (Length)

➸ Length of Rectangle = 27 m

✿ Now Let's Find Area of Rectangle

➸ Area of Rectangle = Length × Breadth

➸ Area of Rectangle = 27 m × 23 m

➸ Area of Rectangle = 27 × 23 m²

➸ Area of Rectangle = 621 m²
