Question

perimeter of a square and a rectangle is same. if the side of the square is 15cm and one side of the rectangle is 18 cm, find the other side of the rectangle?​

Answer 1

ɢɪᴠᴇɴ ᴛʜᴀᴛ:

• Perimeter of a square and a rectangle is same. if the side of the square is 15cm and one side of the rectangle is 18 cm.

ᴛᴏ ꜰɪɴᴅ:

• The other side of the Rectangle

ꜱᴏʟᴜᴛɪᴏɴ:

$\text{Perimeter \: of \: Square =}$ $\tt\bf\red{4 × Side}$

${\bf{Perimeter (Square) = 4 × 15 cm}}$

⠀⠀⠀⠀⠀⠀⠀ ⠀ ⠀⠀⠀⠀⠀⠀⠀⠀ = 60 cm

${\bf{Perimeter \: of \: Rectangle=}}$ $\tt\bf\red{2 × (Length + Breadth)}$

ATQ,

• Perimeter of Rectangle = 2×(L+B)

[Since perimeter of Rectangle and Square was Same:]

• 60cm = 2 (L+B)
• 60cm = 2 (18+B)
• 60/2 = (18 + B)
• 30 = (18 + B)
• B = 30 - 18
• Breadth = ${\bf\blue{12 cm}}$

hєncє, thє σthєr ѕídє σf thє rєctαnglє íѕ 12cm.

$\tt\bf\green{Verification :}$

Perimeter of Rectangle = 2 (12 + 18)

60 cm = 2 (12+18)

60 cm = 2× 30

60 cm = 60 cm

$\boxed{\bf{Since \: LHS = RHS \: our \: calculation \: is \: Correct ✓}}$
