Answer» ion ☆Given :- The perimeter of the rectangle is 400 cm.The length of the rectangle is 50 cm.To Find :- The breadth of the rectangle.The area of the rectangle.Step-by-step-Explaination :- Let,The breadth of the rectangle be b .Now,As we know that :- Perimeter of the rectangle = 2 ( Length + Breadth ) Where,The perimeter of the rectangle = 400 cm The length of the rectangle = 50 cm.The breadth of the rectangle = b Putting the RESPECTIVE VALUE,400 = 2 ( 50 + b ) 400 = 100 + 2b 400 - 100 = 2b 300 = 2b 300/2 = b 150 = b Hence,The breadth of the rectangle is 150 cm.Now,As we know that :- Area of the rectangle = Length × Breadth Where,Length of the rectangle = 50 cm.Breadth of the rectangle = 150 cm.Putting the respective value,Area of the rectangle = 50 × 150 Area of the rectangle = 7500 Hence,The area of the rectangle is 7500 cm². |
