Answer:

B) 72 cm²

Step-by-step explanation:

Area of a trapezoid formula:

[tex]A=\frac{a+b}{2} *h[/tex]

Given:

a = 15

b = 9

h = 6

Work:

[tex]A=\frac{a+b}{2} *h\\\\A=\frac{15+9}{2} *6\\\\A=\frac{24}{2} *6\\\\A=12*6\\A=72[/tex]

Answer:

72 cm²

Step-by-step explanation:

Area of trapezoid :

  • A = 1/2 x (a + b) x h

Solving :

  • A = 1/2 x (15 + 9) x 6
  • A = 3 x 24
  • A = 72 cm²
