<p>The<a>square</a>of a<a>number</a>is the<a>product</a>of the number with itself. The square of 3.5 is 3.5 × 3.5. The square of a number can end in any digit, depending on the number. We write it in<a>math</a>as \(3.5^2\), where 3.5 is the<a>base</a>and 2 is the<a>exponent</a>. The square of a positive and a<a>negative number</a>is always positive. For example, \(5^2 = 25\); \((-5)^2 = 25\). The square of 3.5 is 3.5 × 3.5 = 12.25. Square of 3.5 in exponential form: \(3.5^2\) Square of 3.5 in arithmetic form: 3.5 × 3.5</p>

27
<p>Okay, lets begin</p>
26
<p>Okay, lets begin</p>
28
<p>The length of the wall = 3.5 feet The cost to paint 1 square foot of wall = 3 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = \(a^2\) Here \(a = 3.5\) Therefore, the area of the wall = \(3.5^2 = 3.5 × 3.5 = 12.25\). The cost to paint the wall = 12.25 × 3 = 36.75. The total cost = 36.75 dollars</p>
