Question

A square picture has a frame of length 100 cm. What is the length of each side? What
is its area

Answer 1

Answer:

The length of each side (a) = 25 cm and the area of the square =  625 cm^{2}cm2

Step-by-step explanation:

Given,

A square picture has a frame of length = 100 cm

To find, the length of each side and area of the square = ?

We know that,

Let the length of each side = a

Perimeter of square = 4a

⇒ 4a = 100 cm

⇒ a = \dfrac{100}{4} =254100=25 cm

∴ The length of each side (a) = 25 cm

∴ The area of the square = a^{2}a2

= 25 × 25

= 625 cm^{2}cm2

Hence, the length of each side (a) = 25 cm and the area of the square =  625 cm^{2}cm2 .

Answer 2

Answer:

Sol= Length of picture = 100cm

Shape of picture = Square

Length of each side = 25cm

______________________________________ if the length of picture frame is 100cm so then we will know the ans like this -

1m = 100cm

0.5m = 50cm

so now only we have to know what is the half of 50 cm. here the ans=

50cm - 25 = 25cm

Ans= the length of SQUARE PICTURE FRAME each side is 25cm
