Question

Answer:

The length is 9 cm and width is 6 cm.

Step-by-step explanation:

Given:

Length of a rectangle is 3 more than its Width.

Perimeter of the rectangle is 30 cm

To find:

The length and width of the rectangle

Solution:

Let,

Width = x
Length = x + 3
Perimeter of the rectangle is 30 cm

Perimeter = 2 (Length + Width)

⟶\longrightarrow⟶ 30 = 2 [(x + 3) + x]

⟶\longrightarrow⟶ 30 = 2x + 6 + 2x

⟶\longrightarrow⟶ 30 = 4x + 6

⟶\longrightarrow⟶ 30 - 6 = 4x

⟶\longrightarrow⟶ 4x = 24

⟶\longrightarrow⟶ x = 24/4

⟶\longrightarrow⟶ x = 6

Width = 6 cm

★ Length = x + 3

⟶\longrightarrow⟶ 6 + 3

⟶\longrightarrow⟶ 9

Length = 9 cm

Therefore, the length is 9 cm and width is 6 cm.
