We divide the figure in the following areas:
Area of the two upper triangles:
Area of triangle 1:
At1 = (1/2) * (3) * (2) = 3
Area of triangle 2:
At2 = (1/2) * (6) * (1) = 3
Area of the complete lower rectangle
Ar = (9) * (6) = 54
Area of the lower triangle:
At3 = (1/2) * (2) * (6) = 6
The total area of the figure is:
At1 + At2 + Ar-At3 = (3) + (3) + (54) - (6) = 54
answer:
the area of this figure is 54 units^2

area of the given heptagon is 54 square units.
what is heptagon?
It is a polygon having 7 sides.
coordinates of all 7 vertices are given as:
(-5,3)
(-4,5)
(-2,3)
(3,4)
(4,3)
(4,-3)
(-3,-3)
in the uploaded diagram. heptagon has been split into 5 triangles, called T1, T2, T3, T4, and T5.
Now the area of the heptagon= T1+T2+T3+T4+T5
AreaT1= 3*2/2=3
AreaT2= 3*6/2=9
AreaT5=6*7/2=21
AreaT3=14.5, Using the coordinate formula for the area of a triangle.
AreaT4=6.5, Using the coordinate formula for the area of a triangle.
Total Area= 3+9+21+14.5+6.5= 54
hence, the area of the given heptagon is 54 square units.
