the length of a rectangle is 3 times its
breadth.its perimeter is 64cm.find its length?
Perimeter of rectangle is 2(length + breath
So length is 3w
We get that 2(3w+w) is 64
6w+2w is 64
8w is 64
W is equal to 8 cm and length is 8*3-24
solve for x
2x + 2(3x) = 64
Math
To find the length of the rectangle, we need to first understand the properties of rectangles and their perimeters.
Given information:
Length of the rectangle = 3 times its breadth
Perimeter of the rectangle = 64 cm
Let's assume the breadth of the rectangle as "b".
According to the given information, the length of the rectangle would be 3b.
The formula for the perimeter of a rectangle is: P = 2(length + breadth)
Using the given perimeter, we can set up the equation:
64 = 2(3b + b)
Simplifying this equation:
64 = 2(4b)
32 = 4b
Now, divide both sides of the equation by 4:
b = 8
Since the length of the rectangle is 3 times its breadth, the length would be:
Length = 3 * breadth = 3 * 8 = 24 cm
Therefore, the length of the rectangle is 24 cm.
