Question

Find the area of triangle with base 5 cm and whose height is equal to that of the rectangle with base 5 cm and area 20 cm2

hintHint:

Try to find height using Area of a rectangle = b  h

The correct answer is: 10 cm2


    It is given that base of rectangle = 5 cm and
    Area of the rectangle = 20 cm2
    b cross times h  = 20       ⇒  5  h  = 20
    ⇒  h = 4 cm
    Height of the rectangle = Height of the triangle = 4 cm
    Area of the triangle = 1 half cross times b cross times straight h
    1 half cross times 5 cross times 4 equals 10 cm squared

    An arc of a circle measures 2.4 radians. To the nearest degree, what is the measure, in degrees, of this arc? (Disregard the degree sign when gridding your answer.)

    Note:
    Another answer for this problem could be taken as 137 as well.
    Unitary method is finding out the value of one unit from the relation given and then multiplies the value of the single unit with the number of required units.

    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.
