ANSWER

(a) 364.52 cm

Step-by-step explanation:

Find the radius = 3.5+3.5

= 7.0

Length = 23 cm

Breadth= 23 cm

First find the area of rectangle = lenght × breadth

= (23×23) cm

=529 cm

Second you have to find the area of circle = πr²

= 22/7 × 7²

= 154 cm

Area of the shaded region = area of rectangle - area of circle

= (529 - 154) cm

= 375 cm

375 cm is closest to (a) 364.52 cm

I hope you have understood .
