Question

The perimeter of a rectangular park is 151 m. If its breadth is 29.5 m. find its length

Answer 1

Answer:

The length of the rectangular park is 46 m.

Step-by-step explanation:

The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides. Since opposite sides of a rectangle are always equal, we need to find the dimensions of length and width to find the perimeter of a rectangle. We can write the perimeter of the rectangle as twice the sum of its length and width. The perimeter is a linear measure and has units as meters, centimeters, inches, feet, etc.

The perimeter of a rectangle is the sum of all four sides, which is given by the formula:

$P = 2(L + B)$

where P is the perimeter, L is the length, and B is the breadth.

Given that the perimeter of the rectangular park is 151 m and the breadth is 29.5 m, we can use the above formula to find the length:

$P = 2(L + B)$

$151 = 2(L + 29.5)$

$151 = 2L + 59$

$92 = 2L$

$L = 46$

So, the length of the rectangular park is 46 m.

Answer 2

Answer:

The length of a rectangular park is 46 m

Explanation:

The perimeter of a rectangular park is 151 m.

breadth = 29.5 m

Perimeter  $=2(l+b)$

$2(l+b) = 151\\2(l+29.5) = 151\\2l+59 = 151\\2l = 151-59\\2l =92\\l = 46 m$

Subtraction:

The process of taking items out of a collection is represented by subtraction. For subtraction, use the negative sign. For instance, if four of the nine oranges that are stacked together (as in the image above) are then moved to a basket, the stack will now include five oranges instead of nine. Due to this, 5 is the difference between 9 and 4, which is equivalent to 9 minus 4. Subtraction is a mathematical operation that can be applied with any type of integer, not only natural ones. Subtraction is symbolised by the letter "-". The three numerical parts of the subtraction operation are the minuend, subtrahend, and difference.
