The perimeter of a rectangle is 360 centimetres. If the ratio of its length to its width is 11:4, find the dimensions of the rectangle.​

Step-by-step explanation:

let the length of rectangle be l.

let the width of rectangle be b.

2(L plus B)=360 cm

L plus B=180 cm...equation i)

L/B=11/4

4L=11B...equation ii)

multiply equation i) by 4

4(Lplus B)= 720

4 L plus4 B=720equation iii)

put value of equation ii in equation iii

11 b plus 4 b=720

15 b=720

b=48 cm

put b=48 cm in eq ii)

l=(11/4)\(48)

l=132 cm

length is 132 cm

width is 48 cm

i hope it helps you if not sorry.

Length 132cm, Breadth 48cm

Explanation:

Perimeter = 360cm

Let the length and breadth be x

ATQ

2(11x + 4x) = 360

22x + 8x = 360

30x = 360

x = 360/30

x = 12

Length = 11×12

= 132 cm

Breadth = 4×12

= 48cm
