Question

# Find the area of a piece of cardboard which is in shape of an equilateral triangle of side 12 cm.

Hint:

### Area of equilateral triangle = (side)2

## The correct answer is: 62.35 cm2

### It is given that side of the triangle =12 cm

Area of equilateral triangle = (side)^{2}

= (12)^{2 } = (144)

= 36 cm^{2 }

(Substituting the value of = 1.73, in the above equation)

= 62.35 cm^{2}

### George took a nonstop flight from Dallas to Los Angeles, a total flight distance of 1,233 miles. The plane flew at a speed of 460 miles per hour for the first 75 minutes of the flight and at a speed of 439 miles per hour for the remainder of the flight. To the nearest minute, for how many minutes did the plane fly at a speed of 439 miles per hour?

**Note:**

The relation between speed, distance and time given by the relation above is very important. There could be many such questions formed which ask us to calculate any of the three quantities with certain conditions involved.
