Question

Being successful in mathematics requires understanding as opposed to simple memorization. For example, the formula to find the perimeter of a rectangle is P = 2L + 2W (where L is length and W is width). Memorizing the formula could be helpful. However, if we understand that the perimeter is the distance around the rectangle, we are able to construct the formula and apply it to real-world situations correctly.

Choose another math concept that you have learned. Share your understanding of the concept in your own words.

Explanation / Answer

perimeter of any shape is equal to sum of its sides

for example lets take a rectangle

rectangle has 2 lengths and 2 widths

therefore its perimeter = 2 l + 2w

similarly if we have to find perimeter of a square

square has 4 sides of equal lengths lets say 'a'

so perimeter would be a+a+a+a = 4a
