<p>For the area of a square, we use the formula ‘A = s2’, and for the octagon, we use ‘A = 2(1+\√{2})s2’.</p>
48
<p>For the area of a square, we use the formula ‘A = s2’, and for the octagon, we use ‘A = 2(1+\√{2})s2’.</p>
50
<p>Area of square = \(s2 = 82 = 64\) cm²</p>

<p>Area of square = \(s2 = 82 = 64\) cm²</p>
51
<p>Area of octagon = \(2(1+\√{2}) \times (4)2\) ≈ 84.96 cm²</p>
50
<p>Area of octagon = \(2(1+\√{2}) \times (4)2\) ≈ 84.96 cm²</p>
52
<p>The sum of areas = area of square + area of octagon = 64 + 84.96 ≈ 148.96 cm²</p>
