Question

the dimensions of a photograph are 30 cm into 20 cm what length of wooden frame is needed to frame the picture​

Answer 1

Your answer is here buddy:)

The length of wodden frame required = perimeter of the picture.

As we know that the picture is in the form of a rectangle, we will apply the formula for finding the perimeter of a rectangle here;

Perimeter of rectangle = 2(L+B).

L= 30cm & B= 20cm.

So,

Perimeter of rectangle = 2(30cm+20cm).

= 2×50cm.

= 100cm.

Hence, the length of the required wooden frame is 100cm.

Answer 2

$\huge\underline\mathrm{SOLUTION:-}$

AnswEr:

• The required length of wooden frame = 100 Cm

Given:

• The dimensions of a photograph are 30 cm into 20 cm.

Need To Find:

• What length of wooden frame is needed to frame the picture = ?

ExPlanation:

• Dimensions of the photograph = 30 cm × 20 cm [Given]

Formula used here:

• Perimeter of rectangle = 2 × (l + b)

Putting the values according to the given formula:

• The required length of wooden frame = Perimeter of the photograph

= 2 × (30 + 20) cm

= 2 × 50 cm

= 100 cm

• Hence, the required length of wooden frame is 100 Cm

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

What is Perimeter?

• The length of the boundary of a closed figure is called the perimeter.

• Perimeter of rectangle = 2 × (Length + Breadth)
• Perimeter of a square = 4 × Side

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$
