Math help on finding the area of a trapezoid!

Question

The area of a trapezoid is give by A= 1/2 (b₁ + b₂₎h,

where b_{1= 4 feet and} b_{2= 2 feet and h= 3feet. Find the area of the trapezoid with the dimensions with the given information.}

how do I solve this? what is the correct answer?

Answer 1

A= 1/2(b1+b2)

by putting values b1=4 b2=2 and h=3 on above equation

A= 1/2(4+2)3

1/2* 6* 3

= 9

Answer 2

Hello Maya: Just Substitute thee numbers in place of the letter;

A= 1/2 (b1 +b2) h b1=4 b2-=2 h=3

A= 1/2 (4 + 2) 3

A= 1/2 (6) (3) A= 1/2 (9)

A = 4.5

Hope this helps...Oscar
