Answer:
48 units ^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
b1 = AT = 4*2 = 8 units ( watch the scale)
b2 = SR = 2*2 = 4 units ( watch the scale)
h = The line that S is at the to line that T is at along the x axis
= 4*2 = 8 units ( watch the scale)
A = 1/2 ( 8+4) * 8
= 1/2 *12*8
= 48 units ^2
