Question

4. The length of a rectangle is three times
its breadth. If their perimeter is 96 cm,
find the dimensions of the rectangle.​

Answer 1

Answer:

let the breadth be 'x'

so length = 3x

Perimeter = 2(l+b)

96 = 2(3x+x)

96 = 8x

x = 12

therefore, Breadth of Rectangle = 12 cm

and, Length of Rectangle = 36 cm

Answer 2

Answer:

Let length and width of a rectangle are 3x m and x m respectively, acordingly:-

2.(3x+x)=96

or. 8x=96. = > x=12

Length =3×12 =36 m. Width = 12 m. Answer.
