Question

perimeter=20m area=25 sq. m what will be the length and breadth of the rectangle​

Answer 1

Answer:

length and breadth both are 5

Step-by-step explanation:

let 'l' be length and 'b' be breadth.

so,

perimeter =2(l+b)

20=2(l+b)

l=10-b ---------(1)

area=l*b

l²-10l+25=0

l=5 and b=5

Answer 2

Answer:

l=5 m b=5m

Step-by-step explanation:

given perimeter = 20 =2(l+b)

therefore l + b= 10

area = l×b = 25

by trial and error method first we put 5 as l and 5 as b we get that 5 satisfies all the condition of the question therefore the answer is l= 5m and b = 5m
