The area of the light gray part of the design is 34in²

Area is the measure of the extent of a 2D space enclosed by a shape. It quantifies the region within the boundaries of the shape, expressed in square units.

The area of the light gray part is calculated as

area of big rectangle - area of small rectangle

area of rectangle = l× w

where l is the length and w is the width

area of big rectangle = 7 × 7 = 49 in²

area of small rectangle = 3 × 5 = 15 in²

area of the light gray part = 49 - 15)in²

= 34in²

Therefore, the area of the light gray part of the design is 34in²
