Step-by-step explanation:
Perimeter of the rectangle = 2(l+b)
= 2(48+30)
= 2 × 78
= 156m
Area of the rectangle = l × b
= 48 × 30
= 1440m2
length is increased by 2m = 48+2 = 50m
breadth is increased by 2m = 30+2 = 32m
Perimeter of the rectangle = 2(l+b)
= 2(50+32)
= 2 × 82
= 164m
Area of the rectangle = l × b
= 50 × 32
= 1600m2
Difference in the perimeters is 8m
Difference in the areas is 160m2
hope it helps!!
