Question

A rectangle is 5 times as long as it's breadth and it's perimeter is 220 m. Find its length and breadth​

Answer 1

Answer:

see explanation

Step-by-step explanation:

Let the breadth be x

therfore , length = 5x

According to the given question ,

5x = 220

Therfore, x = 220÷ 5

= 44 m

Answer 2

Answer:

Required length is 91.67 m and breadth is 18.33 m.

Step-by-step explanation:

Given,a rectangle is 5 times as long as it's breadth.

Let, breadth of the rectangle be x m

So, length of the rectangle be 5x m.

It is also given, perimeter of the rectangle is 220 m.

We know, perimeter of the rectangle $= 2 \times (length + breadth)$

For example,if length of a rectangle is 10 m and breadth of the rectangle is 5 m.

So, perimeter of the rectangle

$= 2 \times (10 + 5) \\ = 2 \times 15 \\ = 30 \: m$

Here length is 5x m and breadth is x m and perimeter is 220 m.

According to question,

$2 \times (x + 5x) = 220 \\ 2 \times 6x = 220 \\ 12x = 220 \\ x = \frac{220}{12} \\ x = 18.33$

Required breadth is 18.33 m and length is $(18.33 \times 5) = 91.67 \: m$
