Question

if the length of a rectangle is 3 times of its breadth and perimeter is 96 cm find the length and breadth ​

Answer 1

Answer:

36&12

Step-by-step explanation:

breadth is x

length is 3x

perimeter of rectangle = 96

2(length + breadth)=96

2(3x+x)=96

2×4x=96

8x=96

x=96/8

x=12

length is 36

breadth is 12

Answer 2

Step-by-step explanation:

here,

Let, X

perimeter of rectangle(p)=96cm

length of rectangle (l)=3X

breadth of rectangle(b)=x

we know that ,

2(l+b)=p

[note:- 2(l+b)=p formula]

or, 2(3x+x)=96

or, 2*4x=96

or, 8X=96

or, X=96/8

x=12

Again,

l=3*12

l=36

Length=36

Breadth=12
