Answer» The area of one unshaded rectangle is length = (100-4)/2 = 48mbreath = (40-4)/2 = 18 m so area of one unshaded rectangle = 4818 for 4 unshaded areas it will be = 4(48)(18) =3456m² now area of whole bigger rectangle = 10040 = 4000 m² so, area of shaded portion = 4000-3456m² = 544m² it is wrong ans is 624cm2 how

Answer»

The area of one unshaded rectangle is length = (100-4)/2 = 48mbreath = (40-4)/2 = 18 m

so area of one unshaded rectangle = 48*18 for 4 unshaded areas it will be = 4*(48)*(18) =3456m²

now area of whole bigger rectangle = 100*40 = 4000 m²

so, area of shaded portion = 4000-3456m² = 544m²

it is wrong ans is 624cm2 how
