Question

Find the area of triangle with a base length of 3 units and a height of 4 units

(A) 3 units
(B) 6 units
(C) 7 units
(D) 8 units​

Answer 1

(B) 6 units

Explanation:

In this problem, we would have to multiply 3*4 which equals 12, so the area is 12. But since its a triangle we have to divide it by 2. So the formula is,

b*l=A

A/2 = A

Here is the substitution of the numbers into the formula,

---> 3*4 = 12

---> 12/2 = 6

So the answer is 6 units

Hope this helps! :)
