Questions: Yolanda's property is in the shape of a square. The perimeter of her property is 160 m. She wants to plant a cedar hedge on three sides of her property. If it costs 10 per m of hedge, how much money will she spend?

△ Calculate the cost of planting a cedar hedge on three sides of Yolanda's square property. ○ Determine the length of one side of the square ☼ The length of one side is 40 m. Given the perimeter \( P = 160 \, \text{m} \) and using \( P = 4s \), we solve \( 4s = 160 \) to find \( s = 40 \, \text{m} \). ○ Calculate the total length of the hedge ☼ The total length of the hedge is 120 m. Since each side is 40 m, the hedge on three sides is \( 3 \times 40 = 120 \, \text{m} \). ○ Calculate the total cost of the hedge ☼ The total cost is $1200. With a cost of $10 per meter, the total cost is \( 120 \times 10 = 1200 \). ✧ The total cost of the hedge is $1200. ☺ The length of one side of the square property is 40 m. The total length of the hedge is 120 m. The total cost of the hedge is $1200.
