A wire of 100 cm is cut into two parts and each part is bent to form square.if the sum of the areas of two squares is 425 cm square.find the length of side of two square.

1 answer

if the squares have sides x and y, then

4x+4y = 100 or, x+y=25
x^2+y^2 = 425

My vast experience tells me instantly that 425 = 400 + 25 = 20^2+5^2
