To find out the area of the compound figure, divide the figure into 3 rectangles

see the attached figure to better understand the problem

please give me a minute to draw the figure

step 1

Find out the area of rectangle N 1

A=12*3=36 m2

step 2

Find out the area of rectangle N 3

A=15*3=45 m2

step 3

Find out the area of rectangle N 2

A=(12-7)*(12-6)

A=5*6=30 m2

therefore

the total area is

36+45+30=111 m2

the area is 111 square meters

step 4

Find out the perimeter

P=12+12+15+3+10+6+7+3

P=68 m
