The area of the triangle extension is 12, because the total side length it is on is 18, and the segments to the sides of the triangle are 6 each, meaning 18-12=6, the height of the triangle. The base is given as 4, so 1/2(4x6)=24/2=12.

Add this to the area of the rectangle, 9x18=162, and 162+12=174.

The area is 174.

From 95 to 68 percent decrease
Kay [80]

The decrease is  (95-68) = 27 .

As a fraction, the decrease is  27/95  of the original amount.

To change any fraction to a decimal, do the division:

                             (27)  divided by  (95) = 0.2842...

To change any decimal to a percentage, move the
decimal point two places that ==> way:

                             0.2842...  =  28.42... %
