Answer:
(1) Area = 40 cm^2
Perimeter = 26 cm
(2)Area = 7m^2
Perimeter = 11m
Step-by-step explanation:
(1) length (l) = 8 cm
Breadth (b) = 5 cm
Area of rectangle = length × breadth
Area of rectangle = 8cm × 5cm
Area of rectangle = 40 cm^2
Perimeter of rectangle = 2(l+b)
Perimeter of rectangle=2(8+5) cm
Perimeter of rectangle=2×13 cm
Perimeter of rectangle=26 cm
(2) Length (l)=3.5 m
Breadth (b)=2m
Area of rectangle = length × breadth
Area of rectangle = 3.5 m × 2m
Area of rectangle = 7 m^2
Perimeter of rectangle = 2(l+b)
Perimeter of rectangle = 2(3.5+2) m
Perimeter of rectangle = 2 × 5.5 m
Perimeter of rectangle =11 m
