Marks: +1, -0

How many right angle triangles each having base 15 mm and height 20 mm can be cut from a square sheet having side 3 cm.

Solution:

(4) Area of a right angle triangle

= 1/2 × 15 × 20 = 150 mm^2

Area of square sheet

= 30 mm × 30 mm = 900 mm^2

Number of triangles that can be cut
from the sheet =

{Area of sheet}/{Area of triangle}

= 900/150= 6
