Question

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

Answer 1

2(x+5+x+3)=106
4x+16=106
4x=90
X=45/2=22.5

Answer 2

perimeter of rectangle=106
2(L+B)=106
2(x+5+x+3)=106
2(2x+8)=106
4x+16=106
4x=106-16
4x=90
x=90/4
x=22.5

hope this will help you
