Question

the area of a rectangular field whose length is 3 times breadth,is 384 m square. estimate is length to the nearest Whole number of metre

Answer 1

Heya!!Here is your answer friend ⤵⤵

Let the breadth of the field be X

Then it's length becomes 3X

Area of a rectangle = l× b


$3x \times x = 384 \\ 3x {}^{2} = 384 \\ x {}^{2} = 128 \\ x = \sqrt{128 }$
Hence length = 3√128m

Hope it helps you ✌✌
