Sagot :
Area of the bigger rectangle =(18×8)cm
2
=144cm
2
Area of the smaller rectangle =((30−18)×(8−6))=(12×6)cm
2
=72cm
2
∴ Total area = area of smaller rectangle + area of bigger rectangle =(72+144)cm
2
=216cm

Step-by-step explanation:
the area of bigger rectangle is given by L*W
it simply means that length of larger rectangle multiplied by width of larger rectangle
=20*16
=320m2
hence the path between the lager and smaller rectangle is given by
the path is twice
hence it will be 2*2
=4m
smaller length is
20-4
=16m
smaller width is
16-4
=12
hence area of smaller rectangle
l*w
=16*12
=192m2
hence area of shaded path is given by
=320-192
=128m2
taking larger area of rectangle -the smaller area of rectangle
