Answer:
Step-by-step explanation:
First we write the formula of perimeter for rectangle,
⇒ Perimeter of rectangle = 2L + 2B
We already know the breadth / width and that is 75. We also know the perimeter that is 360m. After inputting both values we will get our length,
⇒ 360 = 2L + 2 ( 75 )
⇒ 360 = 2L + 150
⇒ 360 - 150 = 2L
⇒ 210 = 2L
= 210 ÷ 2 = L
⇒ L = 105m
Checking answer,
⇒ 360 = 2 ( 105 ) + 2 ( 75 )
⇒ 360 = 210 + 150
⇒ 360 = 360
The answer is correct! Please mark as brainliest.

Answer:
105 m
Step-by-step explanation:
as we know
perimeter of rectangle is 2*(l+b)
perimeter=360m
width=75m
length=?
360=2*(l+75)
360/2=l+75
180=l+75
180-75=l
Length=105m
