find the no of squared tin sheets of 30cm that can be cut of from a square tin sheet of side 1.5​

Answer 1

$\huge\mathfrak\red{YOUR ANSWER}$

to find no of sheets of 30 cm that can be cut from a sheet of 1.5 m

first find make 1.5 m into cm

1.5m = 150 cm

so to find no of sheets just ..

$\frac{area \: of \: large \: sheet}{area \: of \: small \: sheet}$

area of large sheet= a²

= 150²

= 22500

area of small sheet= 30²

=900

so sheets can be cut...

$\frac{22500}{900}$

=25

sooo.... 25 sheets can be cut out of it...

Answer 2

Sol: Side of small square tin = 30cm

Area of small square tin = side × side

= 30×30

= 900 cm²

Side of big square tin = 1.5m = 150cm

Area of big square tin = side × side

= 150 × 150

= 22500 cm²

$No.\:of\:square\:tin\:sheets= \frac{area \: of \: big\: square \: tin}{area \: of \: small \: square \: tin } \\ = \frac{22500}{900} = 25$
