Question

length =? breadth =19cm perimeter of rectangle =86cm​

Answer 1

Answer:

perimeter = 2 ( l+b)

so 2 (l+19)=86

l+19=86/2 = 43

l+19= 43

l= 43-19 =24

Answer 2

Step-by-step explanation:

• we know that perimeter of rectangle,
• = 2 ( length+ breadth)
• Given :- breadth= 19cm perimeter= 86cm

perimeter of rectangle = 2 ( l+ b )

86 = 2 ( length + 19)

86/2 = length + 19

43 = length + 19

length= 43- 19

length= 24 cm
