That is a rectangular. So u will use the formula for that

@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

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
