Question 1202975: A wire 80 cm in length is cut into two parts and each part is bent to form a square. If the sum of the areas of the squares is 300 cm?, find the lengths of the sides of the two squares
Answer by math_helper(2461)   (Show Source): You can put this solution on YOUR website!

x = length of each side of first square
y = length of each side of second square
We get:
(1) 4x + 4y = 80 <--- from length information
(2) x^2 + y^2 = 300 <--- from area information
Eq (1) can be solved for y; 4y = 80-4x ==> y=20-x
Substitute "20-x" for "y" in (2), to get:





From WolframAlpha:

x = or x =
If x = , we get y =
(which makes sense, it is the other choice for x above, as the assignments of x and y are arbitrary).
Answer:
The sides of the two squares measure and
