Question

2.
The length of the rectangular hall is 3 m more than double of its breadth. If its
perimeter is 66 metre, find its length and breadth.​

Answer 1

Answer:

Step-by-step explanation:

let breadth of. rectangle be x

length =3+2x

perimeter=66

then 2(L+B)=66

2(3+2x+x)=66

2(3+3x)=66

6+6x=66

x=10.

then length equals to 3+20=23metre

breadth = 20 ÷ 2 = 10
