Answer:
10 cm
Step-by-step explanation:
Let Length be denoted by L and Width be denoted by W
given Length is triple the width , or L = 3W
By definition:
Perimeter of rectangle,
= Length + Length + Width + Width
= 2L + 2W (substitute L = 3W)
= 2 (3W) + 2W
= 6W + 2W
= 8W
Given perimenter is 80 cm,
8W = 80 cm
W = 80 / 8 = 10 cm
Answer:
10 cm
Step-by-step explanation:
If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.
L = 3w
P = 80
Formula: a = l × w
8W = 80 cm
W = 80 / 8 = 10 cm
Therefore, the width of the rectangle is 10 centimeters.
