Question

Find the area of a trapezoid with a height of 4 m and bases of 12 m and 19 m.

Answer 1

A=(h/2)(B1+B2)
just plug in

Answer 2

like this

A = 1/2h(b1 + b2)

Now multiply both sides by 2 to remove the fraction on the right:

2A = h(b1 + b2)

Now divide both sides by h:

2A/h = b1 + b2

Now substract b2 from both sides:

2A/h - b2 = b1

Answer 3

is that good

Answer 4

can someone tell if i did this good

Answer 5

sorry,was busy:
u want 2 find A so A=(4/2)(12+19)=2(31)=62 m^2

Answer 6

thank i did it
