Answer:

- 32 is the ans

Step-by-step explanation:

n = 9 now substituting the values we get,

b(9) = -8 - 2(9-1)

here b(9) is same as a9 i.e the 9th term

Heron’s formula: Area = An equilateral triangle has a semiperimeter of 6 meters. What is the area of the triangle? Round to the

nordsb [41]

Answer:

7 m^2

Step-by-step explanation:

$s = \dfrac{a + b + c}{2}$

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

$s = 6$

$\dfrac{a + b + c}{2} = 6$

$a = b = c$

$\dfrac{a + a + a}{2} = 6$

$3a = 12$

$a = b = c = 4$

$A = \sqrt{6(6 - 4)(6 - 4)(6 - 4)}$

$A = \sqrt{6(2)^3$

$A = \sqrt{48}$

$A = 6.92820...$

$A = 7~m^2$
