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

length = 25m

breadth = 5m

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)

$5 {b}^{2} = 125$

${b}^{2} = 125 \div 5$

${b}^{2} = 25$

$b = 5$

Now, l=5b

          l = 5 x 5

          l = 25

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