Question

By using herons Formula ,

The area of the triangle whose base is 25cm long , and the corresponding height is 10.8 cm .​

Answer 1

Area of Triangle = 1/2 x base x height

Area of Triangle = 1/2 x base x heightArea of Triangle = 1/2 x 25 × 10.8

Area of Triangle = 1/2 x base x heightArea of Triangle = 1/2 x 25 × 10.8Area of Triangle = 135 cm sq.

Answer 2

$Area \: of \: triangle = \frac{1}{2} \times base \times height \\ \: \: \: \: \: \: = \frac{1}{2} \times 25 cm\times 10.8cm \\ \: \: \: \: \: \: = 135 \: cm ^{2}$
