The figure on the right is made up of 5 squares.
Each side of the square is 7 cm.
What is the area of the figure?

Step-by-step explanation:

The formula for calculating the area of a square is given by :

Area =

where is the length of a side .

Therefore , the area of one of the square given implies :

Area =

Area

And since there are 5 squares in all , the area will therefore be :

Area = x

Area =

Therefore: the area of the shape is

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
