Perimeter and area please help

Area = 48m²

Perimeter = 42m

Step-by-step explanation:

There are two rectangles:

1

area:

9*2 = 18m²

2

(12-2)*3 = 10*3 = 30m²

Total:

18 + 30 = 48m²

Perimeter:

2 + 9 + 12 + 3 + (12-2) + (9-3) = 2+9+12+3+10+6 = 42m

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
