Question

Solve the following
(a) Perimeter of a rectangle is 96 m. Its length is 3
times its width. Find its length and breadth.​

Answer 1

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

Answer 2

Answer:

w=45

l Length  

3

P Perimeter  

96

Step-by-step explanation:

Rectangle

Solve for length

l=P

2﹣w

w Width

Enter value

P Perimeter

Let the width of rectangle=x

Then length of the rectangle = 3x

Perimeter of the rectangle = 96cm

2(l+b) = 96m

X+3x = 48

x = 12cm

Breadth of rectangle = 12cm

Length of rectangle = 3×12=36cm
