Solution Steps
00:00Find X
00:03We'll use the formula for calculating the area of a square (side squared)
00:09We'll substitute appropriate values and solve for X
00:13We'll take the square root to isolate X
00:22And this is the solution to the question
Step-by-Step Solution
To solve this problem, follow these steps:
Step 1: Set up the equation based on the given information. The side of the square is given by x+1, and the area formula for a square is (side)2. Thus, we set up the equation as (x+1)2=36.
Step 2: Solve for x. Take the square root of both sides of the equation:
(x+1)=±36 (x+1)=±6
Since x>0 is a condition, only the positive value of x+1 is valid, so x+1=6.
