Question

A metal plate measuring 32 cm by 12 cm is cut up into small square of side length 4 cm. How many squares will be cut?
​

Answer 1

Answer:

Given Dimension of metal plate = 32cm by 12cm.

area of metal plate=32×12

area=384cm2

Given length of square side =4cm.

area of 1 square cut = 16cm2

Total no of squares made=384/16=24

24 squares will be cut form given metal plate.

Hope it helps you.

Answer 2

Step-by-step explanation:

Solution

$\sf \: Area \: of \: metal \: plate \: =32 \times 12 cm^ 2 \\ \sf [As, area \: of \: angle = length \: \times breadth]$

$\sf \: Area \: of \: each \: square \: =side^ 2 =4^ 2 =16 cm^ 2$

Now,number of cut off squares

$\sf\frac{area \: of \: metal \: plate}{area \: of \: each \: square} \\ \sf \: = \frac{32 \times 12}{16} \\ \sf \: = 2 \times 12 \\ \sf \: = 24$
