A woodworker is creating arms for a bench. If the helght of the bench's back is 3 feet tall and the width of the bench's seat Is 1 foot long, what is the length of the arm?

√10 feet ≈ 3.2ft

Step-by-step explanation:

If the helght of the bench's back is 3 feet tall and the width of the bench's seat Is 1 foot long, the length of the arm will be gotten using the pythagoras theorem;

Let l be the required length, Hence;

l² = 3² + 1²

l² = 9 + 1

l² = 10

Square root both sides

√l² = √10

l = √10 feet

Hence the length of the arm is √10 feet

19

Step-by-step explanation:

9 pencils plus 10 pencils is 19 pencils
