Question

how many squares of 25mm×25mm can be cut from 1m×1m sheet?​

Answer 1

Answer:

1600

Step-by-step explanation:

$number \: of \: squares = \frac{area \: of \: sheet}{area \: of \: one \: square} \: \: (units \: should \: be \: same) \\ = \frac{1m \times 1m}{25mm \times 25mm} \\ = \frac{(1 \times 100 \times 10)mm \times (1 \times 100 \times 10)mm}{25 \times 25 \: \: {mm}^{2} } \\ = \frac{1000 \times 1000 \: \: \: {mm}^{2} }{25 \times 25 \: \: \: {mm}^{2} } \\ = 40 \times 40 \\ = 1600 \\ 1600 \: squares \: can \: be \: cut \: from \: the \: sheet.$
