Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.
Step-by-step explanation:
We can set up an average equation in the form, where x is the last score in the fourth quarter:


She needs at least a 95 on the last quarter to average 90 in all four quarters.
