If it’s volume it’s just L x W x H which is 18 x 10 x 2 which is 360cm^3
To find the perimeter, the equation is (w2 + l2 = p)
Where w is width and l is length and p is perimeter.
If you have the width, then you double it for both widths.
Then subtract that number from the perimeter.
150-60 = 90
90 is the remaining number for the lengths. Since both lengths needs to be equal, you split the 90. 45.
You length equals 45.
45(2) + 30(2) = Perimeter of 150.
Your answer is 45.
Once cross multiplied you end up with this:
15x+75=20x−30
Next subtract 20x from both sides.
15x+75−20x=20x−30−20x
−5x+75=−30 -----------> Answer
Now subtract 75 from both sides
−5x+75−75=−30−75
−5x=−105
Now divide by -5 on both sides.
-5/-5x = -105/-5
