Area Triangle Help Question??????

Question

The area of a triangle is 36 square centimeters. Find the measure of the altitude drawn to the base when the base = 8 cm?????

Please help!!!!!!!

Answer 1

1/2 b*h = area right? Been decades since I have had geometry. So, 1/2 8 * h = 36
4 * h = 36
h = 36/4
h = 9

Answer 2

Hey Tom

Area of an triangle equals 1/2 base multiplied by height i.e 1/2bxh
1/2 base x height = 36 cm squared
Base =8cm

1/2(8) x h = 36 cm squared
do the sum on the left i.e divide 8 by 2...
4 x h = 36cm squared
you need to take all the numbers over to one side, to do this divide both sides by 4

4/4 x h = 36/4
On the left hand side 4/4=0 so it disappears leaving only H
H = 36/4
Calculate the sum on the right hand side 36/4 to give you 9
Height ( or altitude) = 9

Check answer 1/2 of 8cm x 9cm = 36cm squared

Answer 3

A=1/2 base times height

Answer 4

area of a triangle is height times base divided by two

36 x 2 = 72, the square around the triangle

72 / 8 cm, the base = a height of 9 cm



edit: 16 is wrong, dont listen to the ^ kid above me

Answer 5

well first of all it depends on what kind of triangle it is.

a right triangle??
a 60-30-90 triangle??
a 45-45-90 triangle??

if it is a right triangle, then the formula for hte area is .5bh
where b=to the base, and h=the height

in this problem the formula would set up to be 36=.5x8xh
if you do the problem you will see that h=9.

Answer 6

The formula for the area of a triangle is A = 0.5*b*h

Sub in what you have:

36 = 0.5*8*h
36 = 4h
36/4=h
9=h

Therefore the height of the triangle is 9 cm.

Answer 7

That is valid for all triangles, the only problem is to find the height when the triangles are not a right angled triangle, because the height is the longer line starting on the base with a 90 degree angle with respect to the base and arriving on the top angle of the triangle. Sometimes is not easy to find the measure of that line.

Answer 8

a = b*h/2 = >
h = 2*a/b = 2*36/8 = 16

Answer 9

The altitude is 9
.5*8*h=36
4h=36
h=9
