Answer:

area = 24 \:  {cm}^{2} .

Step-by-step explanation:

s \:  =  \:  \frac{6 + 8 + 10}{2}  \\ s \:  \:  = 12 \\  \\ s - a = 12 - 6 = 6 \\ s - b = 12 - 8 = 4 \\ s - c = 12 - 10 = 2 \\  \\ area =  \sqrt{s(s - a)(s - b)(s - c)}  \\  =  \sqrt{12 \times 6 \times 4 \times 2}  \\  =  \sqrt{144 \times 4}  = 12 \times 2 = 24 \:  {cm}^{2} .

Answer:

Area  \: of \:  Δ = 24 {cm}^{2}

Step-by-step explanation:

By  \: Herons  \: formula  \\ </p><p>a=10cm, \:  b=8cm,  \: c=6cm \\ </p><p>s= \frac{a + b + c}{2} =  \frac{10 + 8 + 6}{2} = \frac{24}{2} =12cm \\ </p><p>Area  \: of \:  Δ \\ </p><p>= \sqrt{s(s - a)(s - b)(s - c)}  \\  =  \sqrt{12(12 - 10)(12 - 8)(12 - 6)}  \\  =  \sqrt{12 \times 2 \times 4 \times 6}  \\  =  \sqrt{2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 2 \times 3}  \\  =  \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3}  \\  = 2 \times 2 \times 2 \times 3 \\  = 24 {cm}^{2}
