Question

Find the perimeter of a rectangle whose :
(i) length = 40 cm
= 40 cm and breadth = 35 cm
(ii) length = 10 m and breadth = 8 m
(iii) length = 8 m and breadth = 80 cm
(iv) length = 3.6 m and breadth = 2.4 m​

Answer 1

Answer:

perimeter of a rectangle =2(l+b)

2 (40 cm+35 cm)

2(75cm)

=150

Answer 2

Step-by-step explanation:

perimeter of a rectangle =2(l+b) { here l=length and b=breadth }

1) perimeter of the rectangle =2(l+b)

perimeter of the rectangle =2(40+35)=2(75)=150cm

2) perimeter of the rectangle =2(l+b)

perimeter of the rectangle =2(10+8)=2×18=36m

3) perimeter of the rectangle =2(l+b)

perimeter of the rectangle =2(8+80)=2×88=176cm

4) perimeter of the rectangle =2(l+b)

perimeter of the rectangle =2(3.6+2.4)=2×5=10m
