Question

Find the length of the fence required for the playground, if there is an opening for a gate 10 feet long.

• A. 200 feet
• B. 250 feet
• C. 260 feet
• D. 270 feet

Answer 1

The correct option is C 260 feet

The length of the fence required
= Perimeter of the ground - Length of the gate

Perimeter of the ground = 3 × Side
$3\times 30$ = 90 yards
1 yard = 3 feet

90 yards = $90\times 3$
= 270 feet

Length of the fence = 270 - 10
= 260 feet
