A rectangle has dimensions of width = 23.3cm and length = 67.8 cm. A similar rectangle has width = 104.85cm?

Question

What is the length of the similar rectangle?

Answer 1

Let xcm be the length,then

x/67.8=104.85/23.3=>

x=305.1cm

Answer 2

Since the two rectangles are similar, they must have the same relative proportions, i.e., L1/W1 = L2/W2. Therefore, L2 = W2*L1/W1 = 104.85*67.8/23.3 . . . .

So, L2 = 305.10 cm

Answer 3

width of first rectangle = 23.3 cm

length = 67.8 cm    

width of 2nd rectangle = 104.85

so ratio of widths   =  104.85/23.3 = 4.5  

so ratio of lenghts should be 4.5



ratio of lengths = L/67.8 = 4.5     (L = length of second rectangle)

therefore L = 67.8*4.5 = 305.1 cm  

length of rectangle = 305.1 cm
