Question

solve it and pls do calculation

Answer 1

Answer:

Perimeter means the sum of all sides of a closed figure.

here we only know the measure of DE .

but since CB , AJ & GF are parallel to DE ,

let us join CB , AJ and GF to form a single straight line parallel and equal to  DE.

So, CB+AJ+GF=20 cm

perimeter=4+6+3+5+2+20+20=60 cm.
