Question

find the perimeter of rectangle whose (b) area =18cm² breath =6cm ​

Answer 1

Answer:

area = l × b

18 = l × 6

3 = l

perimeter = 2 ( l + b )

= 2 ( 3 + 6 )

= 18

Answer 2

Step-by-step explanation:

First we find the length...

area = l×b ( let l = x)

then, 18 = x × 6

18/6 = x = 3

Perimeter = l×b

2× ( l+b) = 2× (3+6)

18...
