Question

Calculate the area of triangle using the square grid, if each square has side of 1 cm

Answer 1

Correct option is A. Approximately 6 sq.cm

As we can see the figure occupies,

3 complete squares, 3 more than half squares and 63 less-than half-squares

To get the area approximately, we can neglect the less than half squares and take more than-half squares as of full area

So area$$=(3 \times 1)+(3 \times 1)=6 \ sq. \ cms$$ (approx.)
