suppose width is x
x^2=625-400
x^2=225
x=15
width =15
x^2=625-400
x^2=225
x=15
width =15

u can use the Pythagoras theorem so....
(diagonal)square-(length)square=(width)square
therefore 625-400=225
therefore square root of 225 is the width
therefore the width is 15cm
(diagonal)square-(length)square=(width)square
therefore 625-400=225
therefore square root of 225 is the width
therefore the width is 15cm
