To solve for L, you need to isolate/get the variable "L" by itself in the equation:
S = 2HW + 2HL + 2WL Subtract 2HW on both sides
S - 2HW = 2HW - 2HW + 2HL + 2WL
S - 2HW = 2HL + 2WL Take out the "L" in 2HL and 2WL
S - 2HW = L(2H + 2W) Now divide (2H + 2W) to get "L" by itself
I think you can stop here, but if you need or want to simplify:
which looks longer so I don't know if you need to do this
70-35 I believe that’s write
Janice estimate was that it was under by approximately 0.6
units to the actual length of the triangle as she was examining the given
triangle with an estimation that the longest side has a length of 25 units―if
it is a right triangle.
If you looked it up, then you will get the right answer. Just a tip. Your welcome
