Question

length and breadth of arectangular field is in the ratio of 3:2. Its area is 150 m².find its length

Answer 1

Hey...!!!

Let the length and breadth be 3x and 2x.
Area = 150 m square
So,
Length x breath = area of rectangle
3x * 2x = 150
6x square = 150
X square = 150/6
X square = 25
X = 25 under root
X = 5 m

So, length = (3 * 5)m
= 15 m
Breadth = (2 * 5)m
= 10 m

Hope it helps...!!!

Hey☺.Here is your answer u r looking for..

see the attachment..
$let \: the \: ratio \: contain \: x \\ length = 3x \\ breadth = 2x \\ area \: of \: rectangle \: = l \times b \\ 150 {m}^{2} = 3x \times 2x \\ 6 {x}^{2} = 150 \\ {x }^{2} = 25 \\ x = 5 \\ length = 3x = 3 \times 5 = 15$
