A farmer owns a triangular plot in Guntur. He measures the lengths of the sides of his property as 4 ~cm .5 ~cm and 7 ~cm . Then the area of land of the farmer in sq. cm is

Options

  1. A2 6
  2. B4 6
  3. C6
  4. D8 6

Correct answer

B. 4 6

Step-by-step solution

a=4 ~cm , b=5 ~cm , c=7 ~cm aligned & s= a+b+c 2 = 4+5+7 2 =8 ~cm & Area of triangle = s(s-a)(s-b)(s-c) & = 8 4 3 1 & =4 6 ~cm ^2 aligned
