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 Reply
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
