Answer:
I will consider the shaded region apart from the area of the middle figure as the question is not clear.
1648/7 m²
Step-by-step explanation:
First, let us find the area of the larger rectangle,
Area of a rectangle is given by the formula,
= l × b
= 12 × 26
= 312 m²
Now, we will divide the middle region as one small rectangle and two equal semi circles, and then, we will find area of it.
Area of the small rectangle = 16 × 4 = 64 m²
Area of the two equal semi circles having radii as 2 m = 2(πr² / 2)
= 2[22/7 × 2² / 2]
= 22/7 × 4
= 88/7 m² (or) 12.572 m² (approximately)
Now, we will add thearea of the smaller rectangle and the two semi circles,
= 64 + 88/7
By taking LCM,
= 448 + 88
7
= 536/7 m² (or) 76.572 m²
Now, we will subtract the above result from the area of the larger rectangle, then we would get,
= 312 - 536/7
By taking LCM,
= 2184 - 536
7
= 1648/7 m² (or) 235.428 m² [answer]
Hope this helps you !!!
