Respuesta :

A= 1/2(7 + 11)(5)
A = 1/2(18)(5)
A = 45 square units

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
