Question

The ratio of the length and breath of a plot is 4 :3 if the breadth is 40m less than the length what is the perimeter of the plot

Answer 1

Heya!!!!

Here's your answer...

Answer 2

Answer:

Perimeter of the plot is 560 m.

Step-by-step explanation:

let, the length of the plot = 4x

Breadth of the plot = 3x

According to the question,

4x - 40 = 3x

4x - 3x - 40 = 0

4x - 3x = 40

x = 40

So, Length of the plot = 4 × 40 = 160 m

      Breadth of the plot = 3 × 40 = 90 m

Perimeter of plot = 2 × ( length + breadth ) = 2 × ( 160 + 120 )

                            = 2 × 280 = 560 m

Therefore, Perimeter of the plot is 560 m.
