As l=3b

area =lb=75

3b^2=75

b^2=25

b=5 m

perimeter=2(l+b)=2(5+15)=40 m

area =lb=75

3b^2=75

b^2=25

b=5 m

perimeter=2(l+b)=2(5+15)=40 m

The Brainliest Answer!

=>Area of rectangle = length * breadth

=> 75 = x*3x

=> = x²

=> 25 = x²

=> √25 = x

=> 5 = x

So, length = 3 * x=3*5 = 15

And, breadth = x = 5.

Then, perimeter = 2(length + breadth)

perimeter = 2(15+5)

perimeter = 2*20 = 40m
