Question

s=90 a=30 b=20 c=10 find the area with hiron formula ​

Answer 1

Step-by-step explanation:

$using \: herons \: formula \\ area \: of \: triangle \: is \: given \: as \\ Δ = \sqrt{s(s - a)(s - b)(s - c)}$

$Δ = \sqrt{90(90 - 30)(90 - 20)(90 - 10)}$

$Δ = \sqrt{90(60)(70)(80)}$

$Δ = \sqrt{30240000}$

$Δ≈5499 \: square \: units$

Answer 2

Answer:

5499.1

Step-by-step explanation:

= √{90*(90-30)*(90-20)*(90-10)}

= √(90*60*70*80)

= √(30240000)

= 5499.1
