Perimeter is 130 cm
Area is 640 cm²
Perimeter: just add the sides
40+25+30+12 is 107 Then we find the sides we don't know
for the very top side you do 40-30 to find that it is 10cm
Now for the left side it is 25-12 which is 13cm
now you add then 107+10+13=130cm
Now to find the area you do 25×40 which is 1000
now do 12×30 which is 360
finally do 1000-360=640 cm²
