Step-by-step explanation:
Divide in figure (1) ABDE (RECTANGLE) and BCD (CIRCLE)
AREA
1: l×b = 30 × 10 l = 30, b= 10
= 300
300 square is area
1: PERIMETER
2 (l+b) = 2× (30+10)
= 2× 40
= 80
80 is perimeter
PERIMETER r=15
2: 2 × 22/7 × r = 2 ×22/7×15
= 94.28
94.28 is perimeter
AREA
2: 2× 1/2× 22/7 ×r×r= 2×1/2× 22/7× 15 ×15
=707.14
707.14 is area
