Answer:
5
Step-by-step explanation:
I hope this is not a trick question.
As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so
60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60
A = (1/2)(b1 + b2)(h)
A = (1/2)(8 + 14)(4)
A = (1/2)(22)(4)
A = 44 ft^2
