At 10 am the shadow of a post on a pergola is 12 feet long At the same time the shadow of Jimmy who is 6 feet tall is 7 feet long What is the approximate height of the post?
10 ft 3.5 in (to the nearest half inch). There are two similar triangles: The shadows corresponds to one side and have the ratio of 7 : 12 (Jimmy : pole) = 7/7 : 12/7 = 1 : 12/7 So for every 1 of Jimmy's shadow, the pole's shadow is 12/7. The heights are in the same ratio, thus: The height of the pole is 6 x 12/7 ft = 72/7 ft = 10 2/7 ft ≈ 10.29 ft ≈ 10 ft 3.5 in (to the nearest half inch)
The perimeter of a rectangular garden is 24 ft The length is 2 ft more than the width Find the length and the width of the garden?
P = 2L + 2W or P/2 = L + WLet W = x, then L = x + 2, and P/2 = 12. Then,12 = x + 2 + x12 = 2x + 2 divide both sides by 26 = x + 1 subtract 1 to both sides5 = x, so W = 5x + 2 = 5 + 2 = 7, thus L = 7
