To find area so l x w x h
(not sure if I'm right) Using this Formula Part/Whole = %/100
$350/Original Price = 10%/100
cross multiply
10w = 35,000
divide by 10 on both sides
W = $3,500
(seems real high so I'm not sure)
Geometry is another subject in which symmetry is important. <span />
Send it to me and I'd be happy to help! :)
