The perimeter of rectangle is 13 cm and width is 1 3/4 find it's length
(please solve this)

length = cm

Step-by-step explanation:

Perimeter is the sum of the length of all of the sides of a figure. A rectangle has 2 pairs of sides with equal length, which is a 4 sides. Two of those sides have the measure of the width and the other 2 sides have the measure of the length. Since we know the width is , we can multiply that value by 2 (since 2 of the sides are   long) and subtract it from the perimeter, 13:

The sum of the 2 sides that have the measure of the length is cm. To find the length, divide the measure by amount of sides:

÷ 2 =  

The length is   cm.
