Question

the length of a rectangle is (3 x-2) cm and breadth is (X + 4) cm if its perimeter is 60 CM then the value of x is​

Answer 1

Answer:

perimeter of rectangle=2(l+b)

60=2((3x-2)+(x+4))

30=4x+2

28=4x

7=x

length=(3 x-2)= 19

breath=(X + 4) =11

Step-by-step explanation:

hope it's helpful for you

Answer 2

Answer:

7

Step-by-step explanation:

As Perimeter = 2(l+b)

l =3x-2

b =x+4

thus P = 2(3x-2+x+4)

P = 2(4x+2)

60 = 8x +4

56=8x

x= 56/8

x= 7

thus value of x is 7
