​

Answer 1

Answer:

i thought it is about finding the breath because area has given already or it can also ask about perimeter and bbreath both . i will telk you both equation.

Step-by-step explanation:

if we have to find the breath we follow this steps

:area of rectangle= 81cmsq

:length of rectangle=9cm

:so the breath=?

sollution

breath=area/lenght

breath=81/9

breath=9ans

if we have also find the perimeter so we can use this method=2(length+breath)as we already had find out the breath in above equation

the perimeter of rectangle is = 2(l+b)

perimeter=2(9+9)

=2*18=36cm Ans.
