The perimeter of a rectangle is 136 feet . the ratio of its length to its width is 9: 8. what are the dimensions of the rectangle ?

36ft by 32ft, but I'm just guesstimating. 9:8 is a very similar ratio, and you can infer that none of the other ratios are close enough together. But 36 is just larger than 32. Hope this helps.

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
