Question

The perimeter of a rectangle is 84cm if the width of rectanle is 16 cm Find its lenth

Answer 1

26 cm

Explanation:

Formula for Perimeter

• Perimeter = 2(Length + Width)

Solving (given Perimeter is 84 cm and width is 16 cm)

• 84 = 2(Length + 16)
• 42 = Length + 16
• Length = 42 - 16
• Length = 26 cm

Answer 2

L= 26cm

Explanation:

Perimeter= 2(l x w)

Perimeter= 84cm

Width= 16cm

Length=?

84= 2l + 32

2l = 84-32

2l= 52

L= 52/2

L= 26cm
