Please help. I've been stuck for a while on these questions. I'm not good with geometry so I'm very confused.
3:5 is 3+5 = 8 units
2 + 3/8 (4-2) = 2 6/8 = 2 3/4 for x
-3 + 3/8 (2- -3) = -3+ 15/8 = - 1 1/8 for y
parallelogram area = base x height = 120 x 100 = 12 000 sq miles 1 500 000 people / 12 000 sq mile = 1500/12= 125 ppl/sq mile
calculate the area of the triangle 1/2 6 x 8 = 24 then subtract the missing small squares 24 - 7 = 17 sq units
