Answer:
hey mate this is your answer.....
Step-by-step explanation:
Figure 1:-
___________________________________________
Perimeter of figure 1
- Perimeter of rectangle + Perimeter of semicircle
- 2( l + b ) + 2πr /2
- 2 ( 4 + 7) + (2 x 22/7 x 3.5 )/ 2
- 22 + 11
- 33 cm
_______________________________________________
Area of figure 1
- Area of rectangle + Area of semicircle
- (l x b) + ( πr² /2)
- (4 x 7) + (22/7 x {3.5}² /2)
- 28 + 19.25
- 47.25cm²
==========================================================
Figure 2:-
______________________________________________________
Perimeter of figure 2
- Perimeter of rectangle + Perimeter of 2(semicircle) {circle}
- 2( l + b ) + 2πr
- 2 ( 14 + 35) + 2 x 22/7 x 7
- 98 + 44
- 142 cm
__________________________________________________
Area of figure 2
- Area of rectangle + Area of circle
- ( l x b ) + πr²
- (14 x 35) + 22/7 x 7²
- 490 + 154
- 644 cm ²
