Question

the perimeter of rectangle is 9 times its breadth if its lengthis 3 cmis more thantwiceits breadthfind the dimensionsof the rectangle​

Answer 1

Step-by-step explanation:

Let the breadth of rectangle be x

Length =2x+3

Perimeter of a rectangle =2 (L+B)

According to the question

2 (2x+3+x)=9x

2 (3x+3)=9x

6x+6=9x

6=9x-6x

6=3x

6/3=x

2=x

x=2

Breadth of rectangle=x=2cm

Length of rectangle=2x+3=2×2+3=7cm
