The closest i can think of that makes since is 1560=30(52)+b, mainly because
30 x 52 = 1560 so that's what i think it is and if im wrong sry.
The surface area in this equation is 5x4 which is 20

I believe it is 2 feet because area is base multiplied by height. So, 3 x 2/3 is 2.
1angle = 90
4 angles =360
the answer is false
