Step-by-step explanation:

Given that:

• Length of a photograph = 32 cm
• And its breadth = 21 cm

To Find:

• What is the length of the wooden strip required to frame the photograph?

formulas used:

• Perimeter of a rectangle = 2(Length + Breadth)

Concept:

• For getting the length of the wooden strip we have to find the perimeter of photograph by using the formula perimeter of a rectangle.

Finding the length of the wooden strip required:

We know that,

Perimeter of a rectangle = 2(Length + Breadth)

⟶ Perimeter = 2(32 + 21)

⟶ Perimeter = 2 × 53

⟶ Perimeter = 106
