- The perimeter of the rectangle = 82 m.
Given :
- One side of a rectangle = 20 m.
- The length of the diagonal = 29 m.
To Find :
- The perimeter of the rectangle.
Solution :
According to the question,
Diagonal is given in the question and we know that, rectangle has four right angles that means, a rectangle divided into two right angled triangle.
So,
The length of the rectangle is base.
The given one side of a rectangle is perpendicular.
The given one diagonal is hypotenuse.
By pythogoras theorem,
Let,
The base be x.
Given,
Hypotenuse = 29 m.
Perpendicular = 20 m.
Hence, the length of the base is 21 m.
Now, we have to find the perimeter of the rectangle.
We know that,
Perimeter of the rectangle = 2(l + b)
Where,
- l = length
- b = breadth
Now we have,
• length = 21 m.
• breadth = 20 m.
Hence,
The perimeter of the rectangle is 82 m.
