The length of a rectangle is 9/8cm longer than the width. The perimeter of the rectangle is 13+1/4cm. What are the width and length of this rectangle?

width=2 11\16

length= 3 13\16

Step-by-step explanation:

the width is unknown lets name it x

width=x

length=x±9\8

2[x±x±9\8]=13 1\4 cm

x± x =2x

2x×2=4x

9\8×2=9\4

4x±9\4=13 1\4

4x=13 1\4 -9\4

52\4-9\4=43\4

4x=43\4

43\4÷4=2 11\16

so x which is width =2 11\16

length 2 11\16 ±9\8=3 13\16

i believe the answer is letter c) 8
