I have never heard of it sorry
I believe it would be 13p im not for sure though
28°
Since KL and FG are perpendicular they create a 90° angle. 180-90-62=28
We can split this up into 3 rectangles. 2 vertical ones (8 x 3) and one horizontal one in the middle (5 x (8 - 5)
8 x 3 = 24
24 x 2 = 48
5 x (8-5) = 5 x 3 = 15
now add 48 + 15 = 63 cm^2
