Answer 2

Answer:

Given:

The perimeter of a square card board is 1 m.

To find:

Area of square cardboard in cm².

Solution:

⌬ Let side of square cardboard be a.

We know that,

★ Perimeter of square = 4 × side

Therefore,

→ 4 × a = 1 m

→ 4 × a = 100 cm

→ a = 100/4 cm

→ a = 25 cm

Thus, Side of square cardboard is 25 cm.

⠀━━━━━━━━━━━━━━━━━━━━━━━━━

Now, Finding area of square cardboard,

We know that,

★ Area of square = side × side

→ Area = 25 × 25

→ Area = 625 cm²

Hence, Area of square cardboard is 625 cm².
