The total amount needed to purchase the required amount of wire to fence the triangular-shaped garden would be 6, 300 Pesos.
How to find the cost ?
Since all three sides of the garden are 150 cm each, you can simply multiply 150 cm by 3 to find the perimeter:
Perimeter = 3 * 150 cm
= 450 cm
Multiply the perimeter by 7 to account for the turns:
Total Length of Wire = 7 * Perimeter
= 7 * 450 cm
= 3, 150 cm
You need 3, 150 centimeters of wire to fence the garden.
If each centimeter of wire costs 2 pesos, you can find the total cost by multiplying the length of wire by the cost per centimeter:
Total Cost = Total Length of Wire * Cost per Centimeter
Total Cost = 3150 cm * 2 pesos/cm
= 6, 300 pesos
