A painting is painted on a cardboard 19 cm and 14 cm wide, such that there is a margin of 1.5 cm along each of its sides. Find the total area of the margin.
Choose the correct answer:
A) 70 cm²	B) 80 cm²	C) 90 cm²	D) 95 cm²	E) 98 cm²
Length of the cardboard = 19 cm   Breadth of the cardboard = 14 cm   Area of the cardboard = 19 × 14 cm² = 266 cm²   Length of the painting excluding the margin = [19 - (1.5 + 1.5)= 
<gadget id="calculator">19 - (1.5 + 1.5)</gadget>
<output>16</output>
16 cm   Breadth of the painting excluding the margin= 14 - (1.5 + 1.5)= 
<gadget id="calculator">14 - (1.5 + 1.5)</gadget>
<output>11</output>
11 cm   Area of the painting excluding the margin= (16 × 11) cm² = 176 cm²   Therefore, area of the margin = (266 - 176)= 
<gadget id="calculator">(266 - 176)</gadget>
<output>90</output>
90 cm²   ANSWER : 90 cm²
