Area=1/2 X B X H
so is it: .5 x 12 x 5?
and for the second problem?
That is a rectangular. So u will use the formula for that
what formula?
Idk how to do that one..
and btw, .5 x 12 x 5 is 30. that's not an option..
@sabeelio do you know how to do this?
okay so you must use pythagoren theorem since this is a right triangle which is a^2 + b^2 = c^2
a and b are the legs and c is the hypotenus so plug in your values into the equationa nd you'll ge tyour answer
the same theorom should help with your answer for number 2
so what do you think your equation would be?
im confused..
are you saying it'd be: 12^2+ 6^2 = c^2?
yes exactly then just solve for c and that is your asnwer
so uoy have 144 +25 = 169 and the square root of 169 is 13 so that is your answer
now if you apply that to the 2nd question and find the value of c you can get the right answer there as well, it is a rectangle so it is 16 on top and bopttom and 12 on left and right and split into 2 triangleks, so you just find the hypotenus (c) of one of the triangles and you will get your answer
@sabeelio I don't understand what you are saying?
