Question:
Question 9: What is the length of the diagonal of a rectangle having dimensions 3cm and 4cm?
Answer:
Let ABCD is a rectangle having dimensions 4 cm and 3 cm and AC and BD are the diagonals
Now, diagonal AC = √{length2 + breadth2 }
=> diagonal AC = √{AB2 + BC2 }
=> diagonal AC = √{42 + 32 }
=> diagonal AC = √{16 + 9}
=> diagonal AC = √25
=> diagonal AC = 5
So, the length of the diagonal is 5 cm
