The perimeters of two squares are 40 cm and 32 cm. Find the perimeter of a third square whose area is equal to the difference of the areas of the two squares?	Answers: A) 76 cm B) 24 cm C) 88 cm D) 55 cm E) 34 cm
We know perimeter of square = 4(side)   So Side of first square = 40/4= 
<gadget id="calculator">40/4</gadget>
<output>10</output>
10 cm   Side of second square= 32/4= 
<gadget id="calculator">32/4</gadget>
<output>8</output>
8 cm   Area of third Square= 10*10 - 8*8= 
<gadget id="calculator">10*10 - 8*8</gadget>
<output>36</output>
36 cm   So side of third square= 6 [because area of square = side*side]   Perimeter = 4*Side = 4*6= 
<gadget id="calculator">4*6</gadget>
<output>24</output>
24 cm   Answer:24 cm
<result>B</result>
