A spider lived in a room that measured 30 feet long by 12 feet wide by 12 feet high. One day, the spider spied an incapacitated fly across the room, and of course wanted to crawl to it as quickly as possible. The spider was on an end wall, one foot from the ceiling and six feet from each of the long walls. The fly was stuck one foot from the floor on the opposite wall, also midway between the two long walls. Knowing some geometry, the spider cleverly took the shortest possible route to the fly and ate it for lunch. How far did the spider crawl? S. • F
A large lot in a park is going to be split into two softball fields, and each field will be enclosed with a fence. A rectangular lot, wider in width than it is tall in height, is shown. A vertical line begins about halfway across the top of the rectangle extends down to bottom side, splitting the lot in two. The top side length is labeled y. The left and right side lengths are labeled x, as well as the middle vertical line. The parks and recreation department has 2,700 feet of fencing to enclose the fields. What dimensions will enclose the greatest area? (a) Fill in the following equation. ·x + · y = 2,700 (b) Solve the equation in part (a) for y. y = + · x (c) Using A = x · y, write an equation for the area A in terms of x. A = (d) What values of x and y will maximize the area of the enclosures? x = y = (e) What is the maximum area (in square feet)? sq ft
