how many square cards of side 5cm can you cut from a rectangular sheet of paper of length 200cm and width 10cm?

in the width, 2 will fit in the 10cm

in the length, 40 will fit.

number cards: 2*40

To find the number of square cards of side 5cm that can be cut from a rectangular sheet of paper, we need to calculate the area of the sheet and the area of each square card.

The area of the rectangular sheet is given by length multiplied by the width: 200 cm * 10 cm = 2000 cm².

Since each side of the square card is 5 cm, the area of one card is 5 cm * 5 cm = 25 cm².

To find the number of square cards that can be cut from the sheet, we divide the area of the sheet by the area of one card:

Number of cards = (Area of sheet) / (Area of one card)
Number of cards = 2000 cm² / 25 cm²
Number of cards = 80 cards

Therefore, you can cut 80 square cards of side 5cm from the rectangular sheet of paper.
