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

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.
