Answer 2

Step-by-step explanation:

See first find the area of rectangle

So, the area of rectangle is = l*b

= 25 * 15

= 375m²

Now find the area of squares

So, area of a square is = side *side

= 4 * 4

= 16m²

There are four squares so = 4* 16

= 64m²

To find the area of shaded position subtract area of rectangle and area of squares

= 375m² — 64m²

= 311m² Ans...
