Question
The perimeter of a rectangular field is 360m and its breadth is 75m. Find its length.
✓
Answer
Let the length of the rectangle be x m.
Breadth of the rectangle = 75m
Perimeter of the rectangle = 2(Length + Breadth)
= 2(x + 75)m
= (2x + 150)m
It is given that the perimeter of the field is 360m.
⇒ 2x + 150 = 360
⇒ 2x = 360 - 150
⇒ 2x = 210
$\Rightarrow \text{x}=\frac{210}{2}$
=105
So, the length of the rectangle is 105m.
