Question

if the length of rectangle is 4 times of its breath then find length and breath with perimeter 72
​

Answer 1

Answer:

Length = 28.8 (unit), Breadth = 7.2 (unit)

Step-by-step explanation:

Let the breadth of the rectangle be x (unit)

Therefore, the length of the rectangle is 4x (unit)

Perimeter = 72 (unit)

So, according to the problem,

2(length + breadth) = 72 (unit)

or, 2(4x + x) = 72

or, 2 * 5x = 72

or, 5x = 72/2

or, 5x = 36

or, x = 36/5

or, x = 7.2

So, the breadth is x, i.e. 7.2 (unit)

and the length is 4x, i.e. 4 * 7.2 = 28.8 (unit)
