Chapter 8.4, Problem 35E

In Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. In a regular octagon, the approximate ratio of the length of an apothem to the length of a side is 6:5. For a regular octagon with a side of length 15 ft, find the approximate area.

In Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. In a regular octagon, the approximate ratio of the length of an apothem to the length of a side is 6:5. For a regular octagon with an apothem of length 15 cm, find the approximate area.

In Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. In a regular octagon, the measure of each apothem is 4 cm, and each side measures exactly 8(21) cm. Find the exact area of this regular polygon.

In Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. Find the area of a square whose apothem measures 5 cm.

In Exercises 17 to 30, use the formula A=12aP to find the area of the regular polygon described. Find the area of a regular octagon with an apothem of length a = 7.9 ft and each side of length s = 6.5 ft.

In Exercises 27 to 30, find the area of the figure shown. Given: Pentagon ABCDE with DC-DE- AE=AB=5 BC=12 Find: AABCDE

In Exercises 9 to 18, find the areas of the figures shown or described. A 454590 triangle has a leg measuring 6 m.

In Exercises 29 to 32, use the fact that triangles are similar. Rhydian while walking away from a 10-ft lamppost casts a shadow 6 ft long. If Rhydian is at a distance of 10 ft from the lamppost at that moment, what is Rhydians height?

In Exercises 32 to 37, write a paragraph proof. Given: RSandTVarediametersofW Prove: RSTVTS
