Question

the sides of a triangle are 7 24 and 25 cm find its area is in centimetre square

Answer 1

$hey \: mate....... \\ here \: you \: go \: ..........$


$semperimeter = 7 + 24 + 25 \div 2$
$= 56 \div 2$
$= 28$
$now \: according \: to \: heros \: formula$
$area \: of \: triangle$

$\sqrt{s (s - a)(s - b)(s - c)}$
$\sqrt{28(28 - 7)(28 - 24)(28 - 25)}$
$\sqrt{28 \times 21 \times 4 \div \times 3}$
$\sqrt{2 \times 2 \times 7 \times 3 \times 7 \times 2 \times 2 \times 3}$

$2 \times 2 \times 3 \times 7$
$84cm {}^{2}$
