Now, BC=AH+GF+ED
=>BC=8+7+4
=>BC=19m
Perimeter of RectangleABCD=2*(l+b)
=2*(19+11)
=2*(30)
=60m
And, perimeter of SquareGHEF=4*s
=4*7
=28m
So total perimeter of the figure =60+28=88m
Now, area of RectangleABCD =l*b=11*19=209m^2
And area of square GHEF=s*s=7*7=49m^2
So total area of the given figure =209+49=258m^2
Hope this helps you!!!
