Question

The area of a rectangle is 18.3cm^2 and its width is 3.7cm shorter then its length. Calculate the dimensions of the rectangle correct to 3 significant figures.

Answer 1

Area of a rectangle = length * width
given = 18.3
and width = length - 3.7
then 18.3 = (L)*(L - 3.7)
then find L...

Answer 2

you would have to use the quadratic formula then,
and so I am getting that L = -2.81 and 6.51
then plug that in from W = L - 3.7
W = -6.51 and 2.81
(rounded to 3 sig figs of course) :P

Answer 3

thank you
