The perimeter of a rectangle is 50cm. If the length of the rectangle is 15cm, what is the breadth?
Perimeter of rectangle = 2(length + breadth)
50cm = 2(15cm + breadth)
Dividing both sides of the equation by 2:
25cm = 15cm + breadth
Subtracting 15cm from both sides of the equation:
breadth = 25cm - 15cm
breadth = 10cm
The breadth of the rectangle is 10cm.
The perimeter of a rectangle is given by the formula: perimeter = 2(length + breadth).
In this case, we know that the perimeter is 50cm and the length is 15cm.
Substituting these values into the formula, we get: 50 = 2(15 + breadth).
To find the breadth, we can isolate it by dividing both sides of the equation by 2 and then subtracting 15 from both sides:
50/2 = 2(15 + breadth)/2
25 = 15 + breadth
25 - 15 = breadth
Therefore, the breadth of the rectangle is 10cm.
To find the breadth of the rectangle, we can use the formula for the perimeter of a rectangle:
Perimeter = 2(length + breadth)
Given that the perimeter is 50cm and the length is 15cm, we can substitute these values into the formula:
50cm = 2(15cm + breadth)
Now, let's solve for the breadth.
Divide the equation by 2:
25cm = 15cm + breadth
Subtract 15cm from both sides:
10cm = breadth
Therefore, the breadth of the rectangle is 10cm.
