6. 21) A designer is making a medallion in the shape of the letter “L
21) A designer is making a medallion in the shape of the letter “L.” Each unit on the coordinate grid represents an eighth of an inch, and the medallion is to be cut from a 1-in. square of metal. How much metal is wasted to make each medallion? Write your answer as a decimal.
22) Miguel is planning and costing an ornamental garden in the a shape of an irregular octagon. Each unit on the coordinate grid represents one yard. He wants to lay the whole garden with turf, which costs $3.25 per square yard, and surround it with a border of decorative stones, which cost $7.95 per yard. What is the total cost of the turf and stones?
Divide into square, kite, and parallelogram.
24) A machine component has a geometric shaped plate, represented on the coordinate grid. Each unit on the grid represents 1 cm. Each plate is punched from an 8-cm square of alloy. The cost of the alloy is $0.43/cm2, but $.28/cm2 can be recovered on wasted scraps of alloy. What is the net cost of alloy for each component?
23) Fencing costs $1.45 per yard and each unit on the grid represents 50 yd. How much will it cost to fence the plot of land represented by the polygon?
