If the sides of a square are increasing by 3 in., the area becomes 64 in square. Find the length of a side of the original square

Original side of the square =5 inches

Step-by-step explanation:

The side of the square is increasing by 3

Let the original side of the square be 'a' inches.

GIVEN:

       On increasing side by 3 side becomes=a+3 inches

       On increasing the side the area becomes 64 square inches

Area of a square=

As the side cannot be negative, so the original side of the square is 5 inches

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
