The side of square lot is (5x-3) meters. How MUCH fencing material IS needed to encLose the sqUAre lot? If one square meter of the lot costs php15000, what is the cost of the square lot?

This means, find the length of fence material needed.

The material length would be same as the perimeter of the square lot.
This perimeter is 4(5x-3).

COST OF THE LOT:
The area is %285x-3%29%285x-3%29%2Asquaremeters, and the price is given 15000 php/squaremeters.
Cost is 15000%285x-3%29%5E2, units of php.

You can do the multiplication. Note, no final value. You only have enough for the variable expression.
You can multiply or not, depending on what you need or want.
