The width of a rectangle is 15 cm. Its length is 5cm more than twice its width. Find the perimeter of the rectangle. ​

Sagot :

Step-by-step explanation:

Width= 15cm

Length= 2(Width) + 5

Length= 2(15) + 5

Length= 30 + 5

Length= 35

Length= 35cm

Perimeter of a Rectangle= 2(Length) + 2(Width)

P= 2L + 2W

P= 2(35) + 2(15)

P= 70 + 30

P= 100

P= 100cm

The perimeter of the rectangle is 100cm.
