Where P = perimeter, L = length, W = width, and A = area:
A = LW
P = 2(LW)
Hope this helped! :)
Answer:
35
Step-by-step explanation:
40-5=35
35 is left over so it is yout leftover change or money
An isosceles triangle has 2 sides of the same length and one side that's not the same length.
So it says the shortest side, y, is 2.1m, so that means it's the side that is not the same length as the other two sides.
But the other two sides will be the same length. Let's make those 2 sides x.
The equation would be
x + x + 2.1 = 7.5
And with that you can find x.
$2.65
You can get this by subtracting the 7.35 from the 10.
10 - 7.35 = 2.65
The correct answer is the last set of numbers
