Here, we are to find the length and the , breadth of the rectangle
The length of the rectangle = 7 units and Breadth of the rectangle = 3 units
Let
length = l units
Breadth = b units
Perimeter of the rectangle = 20 units
length is the distance measured along the longest dimension of an object
width is the wideness of an object
perimeter refers to the total measurements of an objects
The breadth of a rectangle is 4 units less than its length
If,
Length = l
Then,
b = l - 4
Perimeter of a rectangle = 2(length + breadth)
20 = 2{l + (l - 4)
20 = 2(l + l - 4)
20 = 2(2l - 4)
20 = 4l - 8
20 + 8 = 4l
28 = 4l
l = 28/4
l = 7
b = l - 4
b = 7 - 4
b = 3 units

is the irrational number between 7.7 and 7.9.
Step-by-step explanation:
We have been given two numbers 7.7 and 7.9
whenever we need to find irrational number between any two given numbers
First thing we do is square both the numbers
Here
That is
And
That is
Hence, we can take the number in between 59.3 and 62.4 is 61
since,
Hence, 7.745966..... is the irrational number between 7.7 and 7.9
