The perimeters of two squares are 80 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?	Choose the correct choice from the following answers:
A) 76 cm	B) 24 cm	C) 88 cm	D) 55 cm	E) 73.2 cm
We know perimeter of square = 4(side)   So Side of first square = 80/4= 
<gadget id="calculator">80/4</gadget>
<output>20</output>
20 cm   Side of second square= 32/4= 
<gadget id="calculator">32/4</gadget>
<output>8</output>
8 cm   Area of third Square= 20*20 - 8*8= 
<gadget id="calculator">20*20 - 8*8</gadget>
<output>336</output>
336 cm   So side of third square= 18.3 [because area of square = side*side]   Perimeter = 4*Side = 4*18.3= 
<gadget id="calculator">4*18.3</gadget>
<output>73.2</output>
73.2 cm   Answer:73.2 cm
<result>E</result>
