Answer:
60
Step-by-step explanation:
Area of trapezoid:
[tex]\frac{1}{2}(b1+b2) * h[/tex]
The top base of the trapezoid is given as 7 cm. The bottom base of the trapezoid can be found with 7+5+5 = 17 cm. The height is given as 5 cm. Then, plug these values into the formula.
[tex]\frac{1}{2} (7+17) * 5[/tex]
= [tex]\frac{1}{2} (24) *5[/tex]
= [tex]12*5[/tex]
= 60
