Question

solve it..........................​

Answer 1

Answer:

Step-by-step explanation:

Perimeter=sum of all sides

4x+25=(x+1)+(5x+7)+(2x+1)

4x+25=x+1+5x+7+2x+1

4x+25=8x+9

8x-4x=25-9

4x=16

x=16/4

x=4

Answer 2

Step-by-step explanation:

perimeter of rectangle=4x+25

4x+25=(x+1)+(5x+7)+(2x+1)

4x+25=x+1+5x+7+2x+1

4x+25=8x+9

8x-4x=25-9

4x=16

$x = \frac{16}{4}$

x=4
