Question
If the length of the rectangular sheet is 25 cm and its area is 500 cm2, find the breadth and hence find its perimeter.
The correct answer is: breadth of the given rectanglular sheet is 20 cm & perimeter is 90 cm
Hint:-
i. Area of a rectangle = length * breadth
ii. Perimeter of a rectangle = 2 (length + breadth)
Step-by-step solution:-
From the given information, length = 25 & Area = 500
Let the breadth be x cm
i. Area of the given rectanglular sheet = length * breadth
∴ 500 = 25 * x
∴ 500 / 25 = x
∴ x = 20 cm .................................................. (Equation i)
ii. Perimeter of the rectanglular sheet = 2 (length + breadth)
∴ Perimeter of the rectanglular sheet = 2 (25 + 20) ............................................ (From Equation i)
∴ Perimeter of the rectanglular sheet = 2 (45)
∴Perimeter of the rectanglular sheet = 90 m
Final Answer:-
∴ breadth of the given rectanglular sheet is 20 cm & perimeter is 90 cm.
