Question

find the perimeter of a rectangle whose length and breadth are 15.4 cm and 11.6cm respectively.​

Answer 1

Answer:

p = 2 ( l + b)

2 ( 15.4 +11 .6)

2 * 27 cm

54 cm

Answer 2

Answer:

length = 15.4 cm

breadth = 11. 6 cm

so, perimeter of rectangle =2 (l + b)

= 2( 15.4 + 11.6)

= 2( 27)

= 54 cm

now ,

area = length × breadth

= 15. 4 × 11.6

178.64 cm²
