A rectangle has a width of 10 centimeters. The rectangle's length is 4 times its width. What is the perimeter of the rectangle? centimeters

perimeter of a rectangle = 100cm

Step-by-step explanation:

in order to find the perimeter of a rectangle we need the length and the width of the rectangle. note that we already know the width which is 10cm but we do  not know the value of the length yet . so let us find the width first.

Remember from the question , length is 4 times the width

mathematically,

length = 4 x width

length = 4 x 10

length = 40cm.

now to find the perimeter of the rectangle

the formula for perimeter of a rectangle = 2L + 2W

perimeter of a rectangle= 2 x 40 + 2 x 10

perimeter of a rectangle = 80 + 20

perimeter of a rectangle = 100cm

therefore the perimeter of a rectangle is equal to 100cm

answer: yes youre right.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
