The area of the triangle is bh/2. So we have to "undo" the formula.
The area is 334 Since this is the result of dividing bh/2, let's multiply times 2:
334*2= 668. OK, and 668 is the result of bh. And the problem says that:
b= 2h, so let's rewrite the formula:
2h*h= 668 Multiply on left:
2h^2= 668 Divide both sides by 2:
h^2= 334 Take the square root on both sides:
h= 18.28 is the height, and the base is:
18.28*2= 36.56 is the base.
----------------
Check:
Area of the triangle:
(b*h)/2=
(36.56*18.28)/2= 668.32/2= 334.16 We have a small decimal because of the rounding of numbers but the answer is correct, we have the right answer. Round it off to 334.
