Question

If perimeter and breadth is 5:1rectangles area is 216 find length

Answer 1

Perimeter:Breadth= 5:1

Let the length of rectangle is L

Let perimeter=5x

Breadth=x

We know that Perimeter of rectangle= 2(Length+Breadth)

5x=2(x+L)

5x=2x+2L

2L=2x or L=1.5x

Area of rectangle= Length*Breadth

1.5x*x=216

x^2=144

x=12

Hence Length(L)=1.5*12 = 18
