Three 205

Three metallic bars of lengths 400 cm, 600 cm, and 720 cm are cut into equal pieces. Find the largest possible area of a square that can be made from any of the three bars.

Correct answer:

A =  1600 cm2

Step-by-step explanation:

a=400 cm b=600 cm c=720 cm  400=2452 600=23352 720=24325 GCD(400,600,720)=235=40  x=GCD(a,b,c)=GCD(400,600,720)=40 cm  A=x2=402=1600 cm2
