Question

The dimensions of a lawn is in ratio of 4:1 and its area is 250m square
What is it length of lawn

Answer 1

Answer:

l = 31.62 m

b = 7.905 m

Step-by-step explanation:

$\text{Ratio of length to breadth = 4:1}\\\\\text{Let the length be 4x and the breadth be x}\\\\\text{Then, area = l} \times b = 4x \times x = 4x^2\\\\\text{But, given area = 250 m} ^2\\\\\text{According to question,}\\\\4x^2 = 250\\\\\implies x^2 = \dfrac{250}{4} = 62.5\\\\\\\implies x = \sqrt{62.5} = 7.905 \: approx\\\\\therefore \text{Length = 4x = 4(7.905) = 31.62 m}\\\\\text{And, Width = x = 7.905 m}$
