Answer 2

$\sf{Solution}$

Step-by-step-explanation:-

Given :-

• Area of rectangle lawn = 225m²
• Length = 15m

To find :-

Perimeter of rectangle

Formula to know :-

• Area of rectangle field = l × b
• Perimeter of rectangle = 2(l+b)

Where l = length

b = breadth

Solution ;-

According to question area of rectangle = 225m²

But we know area of rectangle lawn = l×b

So,

l × b = 225m²

15m × b = 225m²

b = 225m² / 15m

b = 15m

So, breadth of rectangle lawn = 15m

Perimeter of rectangle lawn = 2(l+b)

Perimeter = 2(15+15m)

Perimeter = 2(30m)

Perimeter = 60m
