Question

One side of a rectangle is (2x + 5) m and other side is (x + 3) m. The perimeter of the
rectangle is 106 m. find x​

Answer 1

Answer:

15

Step-by-step explanation:

2[(2x+5)+(X+3)= 106

on solving

X=15

Answer 2

$perimeter \: = 2 \times l + b$

$l = 2x + 5$

$b = x + 3$

p = 2[(2x+5) + (x+3)]

p = 2 [2x+5 + x + 3 ]

p = 2[ 3x + 8]

106 = 6x + 16

6x = 90

x = 15
