please become friend  

follow on my insta Arunterifo

Step-by-step explanation:

total perimeter = 2(l+b)

                    24 = 2(x+2+x-2)

                    24 = 4(x)

                     x =6

thus the value of x is 6

length = 8

width= 4

Answer 2

Answer:

Length = l = 8 units

Breadth b = 4 units

Step-by-step explanation:

l = x + 2

b = x - 2

Perimeter of rectangle = 2( l + b)

24 units = 2(x+2 + x-2)

24 = 2 (2x)

24 /2 = 2x

12 = 2x

12 / 2 = x

6 = x

i.e, x = 6

•°• l = x + 2

= 6 + 2

l = 8 units

b = x - 2

= 6 - 2

l = 4 units

I hope this will helps you .
