Answer: £32
Step-by-step explanation: 12 + 4(5) = 32
So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.
STEPS:
1) (n-2)180 = 2520
2) n-2 = 2520/180
3) n-2 = 14
4) n = 16
So the polygon must have 16 sides
Since we know the length (L) to width (W) ratio is 3 to 1, we can put the ratio in the form of a fraction and solve for the unknown length (L’).
Therefore we have L/W = 3/1 = L’/33
Moving the width of 33 to the other side of the equation, we have 3/1 * 33 = L’
99/1 = L’
99 = L’
Therefore the length L’ should be 99cm if the width is 33cm.
