Answer 1

Answer:

375sq. cm

Step-by-step explanation:

length =(3m-2) cm

breadths =(2m-3) cm

by applying condition,

2(3m-2) +2(2m-3) =80

you will get answer after solving this equation,

m=9cm

put the value of m to find length and breadth

l=3(9)-2=27-2=25cm

b=2(9)-3=18-3=15cm

area of rectangle =l ✖ b

therefore,25 ✖ 15

=375 sq.cm
