Question

3. Perimeter of a s rectangle is 54 m and its breadth in 12m find the length.​

Answer 1

Answer:

Step-by-step explanation:

Given,

Perimeter = 54 sq.m

Breadth = 12 m

Perimeter of a rectangle = 2(l+b)

                                   54 = 2 (length + 12)

                                   54 = 2length + 24

                              54-24 = 2 length

                                30/2 = length

Therefore,

Length = 15 m

Answer 2

Answer:

length=15m

2(l+b)=54

Step-by-step explanation:

2(l+b)=54

l+b=54/2

l+b=27

l+12=27

l=27-12

l=15
