there is a triangle with a base of 2.4 m and both sides are 1.7 m. it is a right triangle. what the heck is the answer? i have an answer sheet and i know the answer is 41 but how do you get that answer?
well what the heck is the question!?
i need to find the area
A = B*H/2-what's the height?
It is "almost" a right - angled triangle.
1.7^2 + 1.7^2 = 5.78
2.4^2 = 5.76 , close but not right-angled
Area is(almost) = (1/2)base(height)
= (1/2)1.7(1.7) = 1.4
which is not what you gave.
