If possible, me with this problem. i do not understand what method and such.

14 m^2

Step-by-step explanation:

The method used to find the area of this trapezoid is to put the given numbers into the formula for the area of a trapezoid. That formula is ...

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

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.

The figure shows you that b1 and b2 are 5 m and 2 m (in no particular order) and h is 4 m. Putting these numbers into the formula gives ...

A = (1/2)(5 m + 2m)(4 m) = (1/2)(28 m^2) = 14 m^2

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
