Find the width (w) of a rectangular room with a length (i) of 60 moters and an area (a) of 2,400 square meters.

The answer is 40.

Step-by-step explanation:

1. Divide 2,400 square meters by 60 meters

2. Solve

*To check the answer multiply 40 by 60 and you get 2,400

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
