A square-shaped notice board is of area 100 sq. Ft. If an identical rectangular chart of length 12.5 ft cover the board, then what is the breadth of the chart

8 feets

Step-by-step explanation:

Given that:

Area of rectangular board = 100 ft²

Length if identical rectangular chart = 12.5ft

The are of a rectangle is obtained thus :

Area = Length * breadth

100 = 12.5feets * breath

The breadth = 100 ft² / 12.5 ft

The breadth of the chart = 8 feets

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
