The base of the triangle is 24cm and the area is 228cm^2. I have to find out the height

how???

Please help :) x

A: Kindly see>>> as below:

1-Step: while, the area of a triangle = 1/2 B*H = 228 cm^2

So, you have the result of [228 = 1/2 * 24 * x (to solve for (x) ) ] >>> [ 456 = 24 * x ]

2- Step; therefore: the height [ x = 19 cm ].

Ok

Good Lucks

You can use formula triangles, but I think it's easier to simply make sure you can rearrange. Do you understand what I did above? First you have to memorise the formula area = base x height. Then to rearrange, I find it helps to put b x h on the LHS and area on the RHS. Then you have to isolate the variable you want as subject on the LHS, so get rid of b. Since h when multiplied by b is A, it follows that h alone will be A divided by b. oops, sorry, A = 1/2 b x h, so my answer is wrong, but what I said about rearranging formulae still holds.<br><b>References : </b><br> A = b x h, so just make h the subject like this:

Therefore for your question you simply have to divide 228 by 24 which give you the height of the triangle( 9.5cm) This can be checked by multiplying 9.5*24 which gives 228.
