Find the area. Round to the nearest hundredth if necessary

9514 1404 393

  351.48 cm²

Step-by-step explanation:

Heron's formula can be used to find the area from three side lengths.

  A = √(s(s -a)(s -b)(s -c)) . . . . where s=(a+b+c)/2

  s = (30 +30 +26)/2 = 43

  A = √(43(43-30)(43-30)(43-26)) = √(43(13)(13)(17)) = √123,539

  A ≈ 351.48 . . . square centimeters

choice b is correct
