If a 6 cm × 6 cm square is placed on a triangle, it can cover up to 60% of the triangle. If the triangle is placed on the square, it can cover up to

2/3

of the square. The area (in

cm^2

) of the triangle is:

Solution:

Area of square = 36

cm^2

Let the area of the triangle covers 60% of the triangle.
⇒ x of 60% = 36

{x×60}/{100}

= 36
x = 60

cm^2

Area of the triangle =

2/3

of 60

2/3 × 60

40 cm^2
