Given : Rajat is making a collage. He to paste some square shaped stamps of 5cm each on a square sheet of paper .
He has 16 such stamps
To Find :
i) what will be the area of each stamp
ii) What should be the area of the sheet of paper so that his stamps fit in exactly
iii) Find the length of each side of the sheet
Solution:
square shaped stamps of 5cm
Area of square = (side)²
Area of each stamp = 5² = 25 cm²
Number of stamps = 16
Hence area of 16 stamps = 16 * 25 = 400 cm²
area of the sheet = 400 cm²
length of each side of the sheet = x cm
Area of sheet = x² cm²
x² = 400
=> x = 20
Length of each side of the sheet = 20 cm
