Answer:
45 unit²
Step-by-step explanation:
the yellow shaded area is trapezoid.
And we know area of any trapezoid is represented by A = [tex]\frac{1}{2}[/tex] (sum of bases ) × ( length between bases)
Bases of the trapezoid measure 7 units and 11 units
Length between bases = 5 units.
Area = [tex]\frac{1}{2}(7+11) (5)[/tex]
= [tex]\frac{1}{2}(18)(5)[/tex]
= 9 × 5
= 45 unit²
