Question

Find the unknown values of the square: side=? peri=? Area=49sq.feet​

Answer 1

Area of square = Side x side

49 = side x side

Side = root 49

Side of square = 7 feet

Perimeter of square= 4 x side

P = 4 x 7

= 28 feet

Answer 2

The side of square(a) = 7 feet and the perimeter of square = 28  feet

Step-by-step explanation:

Given,

The area of square = 49 square feet

To find, the side of square(a) = ? and

The perimeter of square = ?

We know that,

Area of square = Side x Side

⇒ $a^{2}$ = 49

⇒ $a^{2}$ = $7^{2}$

⇒ a = 7 feet

∴ The side of square(a) = 7 feet

The perimeter of square = 4 x Side (a)

= 4 x 7 feet

= 28  feet

∴ The perimeter of square = 28  feet

Thus, the side of square(a) = 7 feet and the perimeter of square = 28  feet
