Question

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

Answer 1

Hey mate!!!!
Here is ur ans

The perimeter of square =4×side
100=4×side
side=100/4
=25

Area of square =(side)²
=(25)²
=625

Answer 2

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

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 = $\dfrac{100}{4} =25$ cm

∴ The length of each side (a) = 25 cm

∴ The area of the square = $a^{2}$

= 25 × 25

= 625 $cm^{2}$

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