Question

A Square figure is made from 40 cm. wire. What is the area of the square region?​

Answer 1

Answer:

Perimeter of a square4×sides=40cm (given)

Side of a square=440=10cm

Area of a square=side×side=a2=102=100sq.cm

Answer 2

Given:

Length of wire = $40$ cm

The length of the wire is the perimeter of the square figure since it is the distance around the square.

To find:

Area of the square region

Formula used:

Perimeter of the square =  $4a$ units

Area of the square = Side × Side = $a^{2}$ square units

Step-by-step explanation:

From the given information,

The perimeter of the square = $40$ cm

$4a$ = $40$

$a$ = $\frac{40}{4}$ = $10$

Therefore, each side of the square $a$ = $10$ cm

Area of the square = $a^{2}$

⇒ $10$ × $10$

⇒ $100$ $cm^{2}$

Answer:

Area of the square region = $100$ $cm^{2}$
