the wall around a playground 410m. if one wall along length 80 . what is the length of the wall along its breadth. and what is the area of playground
2(80+x) = 410
area = 80x
250
Given that the total perimeter of the wall around the playground is 410m, we know that one side along the length is 80m.
To find the length of the wall along its breadth, we can subtract the length side from the total perimeter:
410m - 80m = 330m
So, the length of the wall along its breadth is 330m.
To calculate the area of the playground, we need to multiply the length and breadth of the playground. Assuming the length is 80m and the breadth is 330m:
Area = Length x Breadth
Area = 80m x 330m
Area = 26400 square meters
Therefore, the area of the playground is 26400 square meters.
To find the length of the wall along the breadth of the playground, we need to subtract the length of the one wall already given from the total perimeter.
Given:
Total perimeter = 410 meters
Length of one wall = 80 meters
To find the length of the wall along the breadth, we can use the formula for the perimeter of a rectangle, which is: Perimeter = 2(length + breadth).
Let's say the length of the wall along the breadth is "x". Therefore, the perimeter of the rectangle can be expressed as: 2(80 + x) = 410.
Simplifying the equation, we have: 160 + 2x = 410.
Subtracting 160 from both sides, we get: 2x = 250.
Dividing both sides by 2, we find: x = 125.
So, the length of the wall along the breadth is 125 meters.
Now, to find the area of the playground, we multiply the length by the breadth. Therefore, the area of the playground is: 80m * 125m = 10,000 square meters.
