area and perimeter word problems

Area perimeter word issues are the word issues that involve finding area & perimeter of the given shape. An amount of surface occupied by the closed figure is called area. The total distance around the outer surface of a seven dimensional shape is called as perimeter. In this piece of writing they will see few Examples for area perimeter word problem.

Here is the example of area and perimeter word problems:
Solution:

Katharine desires to buy carpet for her rectangle formed bed of 20 by 16 feets. How much carpeting does they need to buy to cover the bed?

Given,

Length of the bed= 20 feet

Covering means they must find the surface area. By formula,

Width of the bed= 16 feet

                                = 20 * 16

Area of the rectangle = l * w

Hence, they needs to buy 320 sq.ft carpet.

                                = 320 sq.ft
Now see the given link to know about formula for perimeter of a rectangle.

percent to decimal

In math, a percent is nothing but a way of writing a number as a fraction of 100 . it's more often denoted with the sign [%]  .For example, [35] [ %]  (read as "thirty-five percent") is equal to [35 / 100] .In order to convert a percent in to a decimal, fundamentally move the decimal point places to the left that is 0.45.In this section they shall speak about 10 percent of decimal form.                                         
Example issues for 10 Percent in Decimal Form:

Example issue 1:

Write 10 percent in decimal form.

Solution:

Move the decimal point places to the left,

 10 percent is 10 per 100.

Therefore 10 percent can be written as 0.1 in decimal form

So that [10/100] = 0.10 zero after the decimal point has no value..
