Pls find area of this shape

A = 42 units

Step-by-step explanation:

A = (h)         Use the equation for area of a trapezoid

A = (12)      Substitute 1 for a, 6 for b and 12 for h

A = 3.5(12)      Add 1 + 6 and divide by 2

A = 42 units

hint: which coefficient is a multiple of 360°?

step-by-step explanation:

the coordinates of a' are (-5, 10)

what i did is i   turned 2 1/2 into an improper fraction which is 5/2. then i multiplied this (the scale factor) by the coordinates of a which is (-2,4).

hope this : )
