Answer:

That will be 7

Step-by-step explanation:

Answer:

(p-2l)/2 = b

Step-by-step explanation:

Formula for perimeter of a rectangle = 2(l + b)

We know,

perimeter = 80

length = 12

if we substitute the values -

p = 2 ( l + b )

p = 2l + 2b

(p-2l)/2 = b

(if you need the width : b = (p-2l)/2  = 80-24/2 = 56/2 = 28cm)
