The perimeter of a rectangle is 30 metres. If it's length exceeds its breadth by 3 metre, then find its length

width --- x

length ---- x+3
2x + 2(x+3) = 30

solve for x

Tho oo

Let the breadth(width)=x

Let the length=x+3
We know that
Perimeter of rectangle=2(length+width)
30m=2((x+3)x)
30m\2=2x+3
15m-3=2x
x=12/2=6m
Length=6+3m=9m

Very nice 👍

If 10 less theeen a number is -10 then the number is

To find the length of the rectangle, we can set up an equation using the given information.

Let's assume the breadth of the rectangle is "x" metres.

According to the given information, the length of the rectangle exceeds its breadth by 3 metres. Therefore, the length of the rectangle is "x + 3" metres.

The formula for the perimeter of a rectangle is: perimeter = 2 * (length + breadth).

In this case, the perimeter is given as 30 metres, so we can set up the equation as follows:

30 = 2 * (x + x + 3)

Simplifying the equation:

30 = 2 * (2x + 3)

30 = 4x + 6

Now, we solve for x:

30 - 6 = 4x

24 = 4x

x = 24/4

x = 6

Therefore, the breadth of the rectangle is 6 metres.

The length of the rectangle can be found by adding 3 to the breadth:

Length = x + 3 = 6 + 3 = 9 metres.

So, the length of the rectangle is 9 metres.
