Question

5)The length of a rectangular hall is 4 meters more than its breadth. If the perimeter of the hall is 56 meters, find its length and breadth. unlimited free points

Answer 1

Step-by-step explanation:

take breadth as x and length as x+4

now,

=> 2(l+b) = perimeter

=> 2(2x+4) = 56

=> x = 12

breadth = 12m. ans!

length = 12+4

= 16m. ans

Answer 2

Answer:

breadth = 12m

length = 16m

Step-by-step explanation:

Let l be length and b be breadth

l = b + 4                         (given in the question)

now let P be perimeter

p = 2(l + b)                     (formula of perimeter)

56 = 2(b + 4 + b)

56 = 2(2b + 4)

56 = 4b + 8

56 - 8 = 4b

48 = 4b

48÷4 = b

12m = b

l = 12 + 4

l = 16m
