Answer:
[tex]13.05cm^2[/tex]
Step-by-step explanation:
Area of a triangle is given a half the product of base by the perpendicular height:
[tex]A=0.5bh[/tex]
Given h=9cm, and b=2.9cm, the area is calculated as:
[tex]A=0.5bh\\\\A=0.5\times 2.9cm \times 9cm\\\\A=13.05cm^2\\[/tex]
Hence, area of the triangle is 13.05 sq cm
