Question

A 10 CM square cloth is cut into four equal Triangles what will be area of each cut Triangle​

Answer 1

Step-by-step explanation:

$area \: of \: a \: triangle = \frac{1}{2} \times x \times y \\ = \frac{1}{2} \times xy \\ 10 {cm}^{2} of \: square \: is \: cut \: into \: 4 \: pieces \\ 10 {cm}^{2} = \: (\frac{1}{2} \times xy) + (\frac{1}{2} \times xy) \\ + (\frac{1}{2} \times xy) + (\frac{1}{2} \times xy) \\ = 2xy \\ xy = 10 \div 2 = 5 \\ area \: of \: a \: triangle = (\frac{1}{2} \times xy) \\ = \frac{1}{2} \times 5 \times 1 \\ 5 \div 2 = 2.5$
