Answer:
Area = 18x + 12
Perimeter = 6x -4 + 12
Step-by-step explanation:
Area = L × W
so, Area = 3x-2×6, which we can write as;
Area = 6(3x-2), which will be;
Area = (6×3x) + (6×(-2))
Area = 18x + (-12), where (+) and (-) will give you (-), so;
Area = 18x - 12
Perimeter(P) = 2(L+W)
P = 2(3x-2+6), which will be;
P= (2×3x) + (2×(-2) + (2×6)
P = 6x + (-4) + 12
P = 6x - 4 + 12
