Question

the area of rectangle is 144cm and it's length is 18cm,find its perimeter ​

Answer 1

Answer:

a=l*b

144=18*b

b=8cm

p=2(l+b)

p=2(18+8)

p=26*2

p=52cm

Answer 2

Step-by-step explanation:

the area of rectangle is length × breadth

144 = 18×b

144/18 = b

breadth = 8

then

the perimeter of a rectangle is 2(length+ breadth)

= 2(18+8)

= 2(26)

= 52
