<p>A rectangle has dimensions of 10 m by 4 m. What is its perimeter?</p>
37
<p>Okay, lets begin</p>
36
<p>Okay, lets begin</p>
38
<p>Use the formula: Perimeter = 2 × (Length + Width)</p>
37
<p>Use the formula: Perimeter = 2 × (Length + Width)</p>
39
<p>Perimeter = 2 × (10 m + 4 m) = 28 m</p>
38
<p>Perimeter = 2 × (10 m + 4 m) = 28 m</p>
40
<p>Therefore, the perimeter of the rectangle is 28 m.</p>

<p>Find the diagonal of a rectangle with a length of 12 inches and a width of 9 inches.</p>
46
<p>Okay, lets begin</p>
45
<p>Okay, lets begin</p>
47
<p>Use the formula: Diagonal = √(Length² + Width²)</p>
46
<p>Use the formula: Diagonal = √(Length² + Width²)</p>
48
<p>Diagonal = √(12² + 9²) = √(144 + 81) = √225 = 15 inches</p>
47
<p>Diagonal = √(12² + 9²) = √(144 + 81) = √225 = 15 inches</p>
49
<p>Therefore, the diagonal of the rectangle is 15 inches.</p>

<p>Use the formula: Area = Length × Width</p>
57
<p>Area = 6 ft × 3 ft = 18 ft²</p>
56
<p>Area = 6 ft × 3 ft = 18 ft²</p>
58
<p>Therefore, 18 ft² of material is needed to cover the table.</p>
