= 3 3/4 m^2

or 15/4 m^2

Step-by-step explanation:

The base is the triangle.  

A =1/2 bh

A = 1/2  (3 1/3 * 9/4)

Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3

A = 1/2 * 10/3 *9/4

Re arranging

   =  1/2* 9/3 * 10/4

 = 1/2 (3) 5/2

 =15/4

Now writing as a mixed number

= 3 3/4 m^2

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
