Answer 2

Question:-

The perimeter of a rectangle is 100m the length of the rectangle is 4m less 5 times its breadth. find its length and breadth.

Provided:-

• Perimeter of a rectangle = 100m
• Length of the rectangle is 4m less 5 times its breadth.

To Find:-

• Find the length and breadth = ?

Solution:-

The question given here, Perimeter of a rectangle is 100m and the length of the rectangle is 4m less 5 times its breadth. Here we have to find length and breadth.

Step by step explanation:

Perimeter of rectangle = 100m

Let length be 5x - 4.

Let Breadth be x.

As we know that,

$\large\sf\purple{Perimeter\:of\: rectangle = 2(length + breadth)}$

Now, substitute the values at their places.

$\sf \implies \: 40 = 2(5x - 4 + x) \\ \\ \sf \implies \: 40 = 12x - 8 \\ \\ \sf \implies \: 12x = 48 \\ \\ \sf \implies \therefore \: x = 4$

Now, find the length and breadth after finding the value of x.

• Length = 5x - 4= 5×4 - 4 = 20 -4 = 16m
• Breadth = x = 4m.

Hence, Length is 16m and breadth is 4m.
