What is the length of a rectangle if the perimeter is 48?
Let L=2W, and P=48, P=2(L+W), P=48, P=2(2W+W), P=2(3W), 48=2(3W) 24=3W W=8 Therefore the length of the rectangle is 16. To check P=16+16+8+8 48=48 true statement. So the value of the length of the rectangle is 16 cm.
What is the length of a rectangle whose perimeter is 48 cm and breadth is 9 cm?
15 cm
What is the length of a rectangle whose perimeter is 48 cm and breadth is 9 cm? Thus, the length of the rectangle is 15 cm.
How do you find the length and breadth of a rectangle when the perimeter is given?
In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) = P/2 – w. Where P = perimeter of the rectangle; and w = width of the rectangle.
How do you find the perimeter with breadth and length?
Multiply the sum of the length and width by two.
- You are able to find the perimeter of the rectangle by adding length and width and multiplying by two because the opposite sides of a rectangle are equal in length.
- Both lengths of the rectangle are the same, and both widths are the same.
How do you find the breadth of a perimeter?
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
How do you find the length and breadth of a rectangle?
To find Length or Breadth when Area of a Rectangle is given
- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.
What is the formula for finding the perimeter of a rectangle?
The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.
