the perimeter of rectangle is 280 m if the radius is 26 less than the length find the length and width
Answers
Solution:
Dimensions of the rectangle:
Let width = w m
length = (w+26)m
i ) Perimeter = 280 m[given]
=>2[length+width] = 280
=> 2[w+26+w] = 280
=> 2w+26 = 280/2
=> 2w+26 = 140
=> 2w = 140 - 26
=> 2w = 114
=> w = 114/2
=> w = 57 m
Therefore,
width (w) = 57m
length = w+26
= 57+26
= 83 m

Given :
- Perimeter of the rectangle = 280 m.
- The width is 26 less than the length of the rectangle.
To find :
- Dimensions of the rectangle =?
Formula Used :
- Perimeter of the rectangle = 2(length + breadth)
Step-by-step explanation :
It is Given that,
Perimeter of the rectangle = 280 m.
The width is 26 less than the length of the rectangle.
Now,
Let, the breadth of the rectangle be, x.
Then, the length of the rectangle be, x + 26.
As We know that,
Perimeter of the rectangle = 2(length + breadth)
Substituting the values in the above formula, we get,
280 = 2 (x + x + 26)
280 = 2(2x + 26)
280 = 4x - 52
4x = 280 - 52
4x = 228
x = 228/4
x = 57.
Hence,
The breadth of the rectangle, x = 57 m
Then, the length of the rectangle, x + 26 = 57 + 26 = 83 m
