What is the area of a triangle?

Question

if one side is3" and the other side is 4"?
How do you find an area, didnt learn in class

Answer 1

Hi, hope this helps....... Ill give you the link, its best.

However a triangle equal 1/2 the base, times the height.

So, obviously, you need, if your trying to figure out the answer for a specific triangle, those things, base, height (dimensions in general..) Best, Dave

Answer 2

Hi. There is a right triangle which has sides of 3", 4" and 5". The two sides 3 and 4 get multiplied to make 12 square inches and this is cut in half by the 5 " hypotenuse. 6 square inches is the answer.

Answer 3

There's not enough information.

The area of a triangle is

A = (1/2)bh, where b is the base and h is the height.

**IF** the base is 3 and the height is 4, the area of the triangle would be

A = (1/2)(3)(4)
A = (1/2)(12)
A = 6

Answer 4

Area of a right triangle is 1/2 * L * H as it is 1/2 of a rectangle.

In this case, 6.

Answer 5

1/2 the base times the height

Answer 6

Triangle formula for area

A = 1/2 bh

A = 1/2 (3)(4)

A = 1/2(12)

A = 12/2

A = 6

The area equals 6

Answer 7

Brad's answer is clearly insufficient.

You did not give enough information. What kind of triangle? If a scalene, what length is the third side? If isosceles, which side is like the third side?

Answer 8

If it is a triangle you would have to multiply by the base and divide by 2.

Answer 9

the formula is
Length x Breadth /2

note: the length and breadth must be perpendicular i.e. at 90 degrees
