A trapezoid has a base of 5cm, a height of 4cm. What is the area?

area = 16 cm²

Step-by-step explanation:

area of rectangle = 3x4 = 12

area of triangle = 2x4x0.5 = 4

12 + 4 = 16 cm²

another way is :

1/2(b1+b2)(h) = area

1/2(3+5)(4) = 16 cm²

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

i don't even know man. edge inuity be messing with us. i had to ask a question too.
