Question

the. parameter of a rectangle is 56 metres and its length is 16 metres find its breadth.​

Answer 1

Answer:

12 is your answer.

Step-by-step explanation:

Perimeter of Rectangle= 2(l+b)

56= 2(16+b)

56= 32+2b

2b= 56-32

2b= 24

b = 24/2

b = 12

Hope it is helpful.

Answer 2

First find its breadth

Breadth=(perimeter÷2)- length

(56÷2)-16=28-16=12

Breadth is 12m

Now we find the area

Area of a rectangle= Length× breadth

=(16×12)m2=192m2

cost of levelling is =$(192×3)=$ 576
