Question

The conference hall was rectangular in shape with the length of being 5 times than that of the breadth if total area covered was 125 square metre then what were the exact dimensions of the floor of the hall​

Answer 1

Answer:

Answer:

length = 25m

breadth = 5m

Step-by-step explanation:

length = 5 x breadth

l = 5b …. ( eq. 1)

area = 125 sq. m

area of rectangle = l x b

l x b = 125

5b x b = 125 ( from eq. 1)

5 = 125

b²= 125 ÷ 5

b²= 25

b = 5

Now, l=5b

         l = 5 x 5

         l = 25

therefore, the length is 25m and breadth is 5m

Step-by-step explanation:

Answer 2

Answer:

The exact dimensions of the hall are Length=25m and breadth=5m

Step-by-step explanation:

Given that,

The conference hall was rectangular in shape with the length being 5 times that of the breadth and total area covered was $125m^{2}$

Let the length and breadth of the conference hall be l and b respectively.

Hence,according to given question we have an relation $l=5b$

The area of an rectangle is product of length and breadth.Hence,mathematically we write $A=lb$

Substituting the value of area and length in above relation we get,

$125=5b\timesb= > b^{2}=25= > b=5m\\l=5b=5\times5=25m$

Therefore,the exact dimensions of the hall are Length=25m and breadth=5m
