Find the perimeter and area of a rectangle whose
length = 25 cm and breadth = 18 cm
length = 27 cm and breadth = 17 cm
length = 7.2 m and breadth = 80 cm
Answers
Length =25cm & breadth =18cm
Perimeter =2(l+b)=2(25+18)=86cm
Area =lb=(25)(18)=450cm
2
.
Step-by-step explanation:
1. length = 25 cm and breadth = 18 cm
perimeter= 2(length+breadth)
= 2(25+18)
= 2(43)
= 2x43
= 86c.m.
area of a rectangle = length x breadth
= 25x18
= 450 c.m²
2. length = 27 cm and breadth = 17 cm
perimeter= 2(length+breadth)
= 2(27+17)
= 2(44)
= 2x44
= 88c.m.
area of a rectangle = length x breadth
= 27x17
= 459 c.m²
3. length = 7.2 m and breadth = 80 cm
perimeter= 2(length+breadth)
= 2(7.2+80)
= 2(87.2)
= 2x87.2
= 174.4c.m.
area of a rectangle = length x breadth
= 7.2x80
= 576 c.m²
