Answer:
r=4
Step-by-step explanation:
-4( r + 2) = 4(2 - 2r)
Distribute
-4r -8 = 8 -8r
Add 8r to each side
-4r+8r -8 = 8 -8r+8r
4r -8 =8
Add 8 to each side
4r-8+8 =8+8
4r = 16
Divide each side by 4
4r/4 = 16/4
r =4

Answer:
38 in²
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A = h (a + b)
where a, b are the parallel bases and h the perpendicular height
here a = 12, b = 7 and h = 4, hence
A = 0.5 × 4 × (12 + 7) = 2 × 19 = 38 in²
