Answer 1

The expression of X in terms of l is X = √5 l

How to calculate the diagonal of a rectangle

According to the given information:

• Length = w
• If length l is twice as long as the width, then l = 2w

Determine the diagonal using the Pythagoras theorem:

X² = w²+(2w)²
X² = w² + 4w²

X =√5w²
X = √5 w

Replace w with l

X = √5 l

Hence the expression of X in terms of l is X = √5 l
