Question

A rectangle and Square have the same perimeter 100 cm .find the side of the square. if the rectangle has a breath of 2 cm less than that of the square. find the breadth length and area of the rectangle ?​

Answer 1

Answer:

Length of Rectangle = 27 m

Area of rectangle = 621 m²

Step-by-step explanation:

Solutions :-

Given :

Perimeter of rectangle = Perimeter of Square = 100 m

Find the side of the square :-

Perimeter of Square = 4 × side

=> 100 m = 4 × Side

=> Side = 100/4 = 25 m

Breadth of rectangle = (side of square - 2) m

= (25 - 2) m = 23 m

Let the length of rectangle be x

Find the length of rectangle :-

Perimeter of rectangle = 2(Length +Breadth)

=> 100 = 2(x + 23)

=> 100/2 = x + 23

=> 50 - 23 = x = 27 m

Find the area of rectangle :-

Area of rectangle = (Length × Breadth) sq. units

= (27 × 23) m²

= 621 m²

Hence,

Length of Rectangle = 27 m

Area of rectangle = 621 m²

Answer 2

Answer:

Side of the square is 20. Breadth is 18 cm, length is 22.22 cm. Area of rectangle is l x b = 399.96 cm sq
