David would have to save for 7 weeks in order to have enough money for his bike.
Best guess is it’s the second one but I believe it’s between A and B sorry If I’m wrong.
Can you go deeper into the question?
A) Perimeter of Trapezium = 8+5+6+15.5
= 34.5in
Area= 1/2*(a+b)*h
=1/2*(8+15.5)*4
=47in^2
B)Perimeter= 12+6+8.5
=26.5mm
Area=1/2*b*h
=1/2*12*4
=24mm^2
I think the area of this triangle is 27.1 square cm. Hope it help!
