Answer 1

area of the square chart is
$60 \times 60 = 3600sq.cm$
area of card is
$8 \times 5 = 40sq.cm$
area of the sheet required is
$3600 \div 40$
answer will be
$90 \: cards$

no chart paper will be left

Answer 2

Answer:

1) 90 cards

2) 0 sq-cm; No chart paper left

Step-by-step explanation:

Anita wants to make rectangular cards measuring 8 cm×5 cm . she has a square chart paper of side 60 cm . To find that how many complete cards can she make from this chart,

find the area of square first;

Area of square = side × side

$= 60 \times 60 \\ \\ = 3600 \: {cm}^{2}$

Dimensions of Rectangular cards:

length = 8 cm

breadth = 5 cm

Area of Rectangular cards = length × breadth

$= 8 \times 5 \\ \\ = 40 \: {cm}^{2}$

Number of cards so formed from square sheet

$\frac{area \: of \: square \:sheet }{area \: of \: rectangular \: cards} \\ \\ = \frac{3600}{40} \\ \\ = 90 \: cards$

Hope it helps you.
