Question

The perimeter of a rectangular field is 360m and it's breadth is 75m .If it's length

Answer 1

110 m

Step-by-step explanation:

Perimeter is 360 = 2l + 2b

b= 75m so 360 - 150 = 2l

2l = 210

length = 110 m

Answer 2

The length of the rectangular field is  105 meters

Step-by-step explanation:

Given as :

The perimeter of rectangular field = P = 360 meters

The breadth of the field = b = 75 meters

Let The length of the field = l meters

According to question

∵   perimeter of rectangular field = 2 ( length + breadth )

So,  2 ( length + breadth ) = 360

Or, length + breadth = $\dfrac{360}{2}$

Or, l + b = 180

Or, l + 75 m = 180 m

∴    l = 180 - 75

i.e  l = 105 meters

So, The length of the rectangular field = l = 105 meters

Hence, The length of the rectangular field is  105 meters Answer
