Question

the length of the one side of a rectangle is three metre longer than its adjacent side and the perimeter of a rectangle is 66 find its length and breadth​

Answer 1

Step-by-step explanation:

length (l)=3+breadth (b)

2 (l+b)=66

l+b=33

3+2b=33

2b=30 b=15 and l=15+3=18

Answer 2

Step-by-step explanation:

let breadth= x

length = x+3

perimeter=2(l+b)

=2(x+3 +x)

=2(2x+3)

but perimeter=66m(given)

so,

2(2x+3)=66

(2x+3)=66/2

2x+3=33

2x=33-3

2x=30

x=30/2

x=15

so breadth=15m

length=x+3=15+3=18m

hence the answer
