The side of the square lot is (5x-3) meters. How many meters of fencing materials are needed to enclose the square lot? If one square meter of the lot costs Php15,000,what is the cost of the square lot?
well, there are 4 sides, right?
for the cost, just multiply area by cost/m^2
Solution plss
To find the perimeter of the square lot, you need to multiply the length of one side by 4 (since there are four sides in a square).
Given that the length of one side of the square lot is (5x-3) meters, the perimeter would be:
Perimeter = 4 * (5x-3)
To calculate the cost of the fencing materials, you need to multiply the perimeter by the cost per meter of fencing. In this case, we are given that one square meter of the lot costs Php15,000.
Cost of fencing materials = Perimeter * Cost per meter
Now we can substitute the values into the formulas:
Perimeter = 4 * (5x-3)
Cost of fencing materials = Perimeter * Php15,000
Simplifying the expression for the perimeter:
Perimeter = 4 * (5x-3)
= 4 * 5x - 4 * 3
= 20x - 12
Substituting the expression for the perimeter into the formula for the cost of fencing materials:
Cost of fencing materials = (20x - 12) * Php15,000
= 15,000 * 20x - 15,000 * 12
= 300,000x - 180,000
Therefore, the number of meters of fencing materials needed to enclose the square lot is 20x - 12 meters, and the cost of the square lot is 300,000x - 180,000 Php.
To find the amount of fencing materials needed to enclose the square lot, we need to determine the perimeter of the square. The perimeter of a square is found by adding the lengths of all four sides.
In this case, the side of the square lot is given as (5x-3) meters. Since all sides of a square are equal, we can say that all four sides are (5x-3) meters long.
To find the perimeter, we multiply the length of one side by four:
Perimeter = 4 * (5x-3)
To determine the cost of the square lot, we need to find the area of the lot and multiply it by the cost per square meter.
The area of a square is found by squaring the length of one side. In this case, the formula for area is:
Area = (5x-3)^2
Then, we multiply the area by the cost per square meter:
Cost = Area * Php15,000
To calculate the final answers, you will need to substitute the given value for x into the formulas and perform the necessary calculations.
