Question

If two equilateral triangles each of side length 6 m are joined to form a quadrilateral, then the perimeter of the figure so formed is _____

• A. 36 m
• B. 24 m
• C. 12 m
• D. 18 m

Answer 1

The correct option is B 24 m

The below given figure shows a quadrilateral formed by joining two equilateral triangles each of side length 6 m :
$\because$ Perimeter of polygon = sum of sides of the polygon
Hence, perimeter of the quadrilateral
= (6+6+6+6) m
= 24 m.
