Question

The perimeter of a rectangle is 66 metre.The length of the rectangle is one more metre than thrice the breadth. What is the length and breadth??

Answer 1

Answer:

check below

Step-by-step explanation:

let the breadth be x m

Now ,

perimeter of rectangle = 66m

2l + b =66m

2 (3x+1) + x = 66

6x + 2 + x = 66

7x + 2 =66

7x = 66- 2 = 64

x = 64/7 = 9.13

breadth = 9.13 m

length = 3×9.13 +1 = 27 .39 + 1

= 28.38 m

Answer 2

Answer:

Let the breath =x

and lenth =3x+1

Perimeter =66m

2(x+3x+1)=66m

2×(4x+1)=66m

8x+2=66

8x=66-2

x=64/8=8

Lenth=3x+1=(3×8)+1=25

Breadth =x=8
