Answers
Given -
- Length of rectangle = 9.25m
- Breadth of rectangle = 8.50m
To find -
- Perimeter of the rectangle
Solution -
Perimeter of rectangle = 2(l + b)
Where,
L = Length
B = Breadth
On substituting the values -
Perimeter of rectangle = 2(9.25 + 8.50)m
Perimeter of rectangle = 2(17.75)m
Perimeter of the rectangle = 35.5m²
The perimeter of the rectangle is 35.5m²
Other formule -
• Area of rectangle = L × B
• Area of square = side × side
• Perimeter of square = 4 × side
• Area of triangle = 1/2 × base × altitude\height
• Perimeter of triangle = a + b + c

Length and breadth of a rectangle are 9.25 m & 8.50 m. What is the perimeter of the rectangle.
- Length of rectangle = 9.25 metres.
- Breadth of rectangle = 8.50 metres.
- Perimeter of rectangle.
- Perimeter of rectangle = 35.5 metres
- Length as L.
- Breadth as B.
- Perimeter as P.
- Perimeter of rectangle = 2(l+b)
- This question says that there is a rectangle. It's length and breadth are given respectively 9.25 m and 8.50 m. Now, it says that we have to find the perimeter of rectangle.
- To solve this question we have to use the formula to find perimeter of rectangle that is 2(l+b). Afterthat according to this formula we have to put the values. We have to put 9.25 as l and 8.50 as b. After putting them we get 2(9.25 + 8.50). Now add the digits we get 17.75 afterthat multiplying this by 2 we get 35.5 m as our final result . Thus, we get 35.5 metres as the perimeter of rectangle.
According to this question, we already know that what is given or what to find. We have given with l and b and we have to find the perimeter.
So, let's see formula to find perimeter of rectangle again.
- Perimeter = 2(l+b)
Where,
- l is length.
- b is breadth.
- p is perimeter.
Putting the values we get the following results.
➝ P = 2(l+b)
➝ P = 2(9.25 + 8.50)
➝ P = 2(17.75)
➝ P = 35.5 metres.
Henceforth, perimeter of rectangle is 35.5 metres.
