Here two of given figures (I) and (II) are similar in
dimensions.
And also figures (III) and (IV) are similar in dimensions.
∴ Area of figure (I) = Area of trapezium = 1/2(a+b)xh
= 1/2(28+20)x4=1/2x48x4=96cm²
Also Area of figure (II) = 96cm²
Now Area of figure (III) = Area of trapezium = 1/2(a+b)xh
= 1/2(24+16)x4=1/2x40x4=80cm²
Also Area of figure (IV) = 80 cm²
