Mwakio fenced a rectangular piece of land measuring 15 m and 31 m. He used six strands of wire, leaving a space of 5 m for the gate. What was the total length of the wire used?

A. 552 m
B. 522 m
C. 547 m
D. 87 m

---

The correct answer is [B]

- The perimeter of the land = 2 [L + W]
= 2 [ 15 + 31 ]
=2 [ 46]
= 92 m
92m -5m (gate)
= 87 m
Six strands= 87 x 6
= 522 m
