Question 919664
Since we are not given an angle for each triangle, we assume we are working with right triangles.
We use the formula for the area of a triangle, A = 1/2*b*h.  Let the base be equal to 60 or 90 and we have for the two triangles,
2133 = 1/2 * 60 * h1
60h1 = 4266
h1 = 71.1
4800 = 1/2 * 90 * h2
90h2 = 9600
h2 = 106.7
note that 60/90 = 2/3 and 71.1 / 106.7 = 2/3
we want the side opposite 90 degrees which is the hypotenuse
note formula to use is a^2 + b^2 = c^2
60^2 + 71.1^2 = c1^2
c1^2 = 8655.21
c1 = 93.03
90^2 + 106.7^2 = c2^2
c^2 = 19484.89
c2 = 139.59
note that 93.03 / 139.59 = 2/3
the sides opposite the 90 degree angle for each triangle are 93.03 and 139.59
and the sides for each triangle are
60, 71.1, 93.03 and 90, 106.7, 139.59
