Mr. Alvarez needs a board of length 5.83 feet
Step-by-step explanation:
Step 1 :
Given
Width of the gate = 3 feet
Height of the gate = 5 feet
We need to find the board's length to fix across the diagonal of the gate
Step 2 :
The gate is in the shape of a rectangle with sides 3 and 5 feet. So we need to find this rectangle's diagonal . Let l be the diagonal's length
Using Pythagoras theorem,
l² = 5² + 3² = 25 + 9 = 34
=> l = √34 = 5.83 feet
Step 3 :
Answer :
