Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan’s height in centimeters?

Answer:

Thus the answer is 127

Step-by-step explanation:

4 feet = 48 inches. 2.54 = 1 inch.

It is found that Joan's  height is 127 centimetres.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .

First we change her height to inches;

1 Foot = 12 Inches

Therefore, 4 Feet = 4 x 12 = 48 inches

The Total height in inches =48 inches + 2 Inches = 50 inches

Now, we have gotten her height in inches, change  to centimetres.

We have that;

1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Hence, Joan's height is 127 centimetres.
