Question

Find area of the triangle whose sides are 7 cm 24 cm 25 cm

Answer 1

Area = √p(p-a)(p-b)(p-c)

--------------------------------------------------------------------------------

Find p:

p= (7 + 24 + 25) ÷ 2

p = 28 cm

--------------------------------------------------------------------------------

Find area:

area = √28(28- 7)(28-24)(28-25)

area = √7056

area = 84 cm²

--------------------------------------------------------------------------------

Answer: The area is 84 cm²

Answer 2

Hiiii......friend

The answer is here,

Area of the triangle ,

S = (a+b+c)/2.

=> (7+24+25)/2

=> 28.

By herons formula,

$= > \: \sqrt{s(s - a)(s - b)(s - c)}$

$= > \: \sqrt{28(28 - 7)(28 - 24)(28 - 25)}$

$= > \: \sqrt{28(21)(4)(3)}$

$= > \: \sqrt{7 \times 4 \times 7 \times 3 \times 4 \times 3}$

$= > \: 7 \times 4 \times 3$
$= > \: 84 {cm}^{2}$

;-)Hope it helps u.
