I’ve got you. The first one that has no black space should be 75m (you can find a triangles area by doing the base times the height, and then halving the product of that btw (like 6 times 5 equals 30, then cut 30 in half to get 15 as the area).) The second one with the black space should be 72m (all I did to get that was do 8 times 12 for the area of the rectangle (96m), then subtract the area of the black triangle (24m) from that to get 72m). I hope this helps!
