Solution

Step 1: Finding the area of the chart paper -
Side of the square chart paper = $60 cm$
Area of the chart paper = $60 \times 60 = 3600 c m^{2}$
Step 2: Finding the area of one rectangular card -
The length of the card = $8 c m$
The breadth of the card = $5 c m$
Area of the rectangular card = $8 \times 5 = 40 c m^{2}$
Step 3: Finding the number of the cards -
Number of cards = $Areaofchartpaper÷Areaofrectangularcard$
= $3600 \div 40$
$4090 3600 - 360__000000_X X X$
Quotient = $90$ and remainder = $0$
Hence, $90$ complete cards can she make from this chart and no chart will be left.
