Question

A square mirror if side 30 cm needed to be framed. What is the the length of frame needed

Answer 1

$\large\boxed{\mathtt{ \pink{ᴀnswer}}}$

${ \sf{side \: of \: square \: mirror = 30cm}} \\ \sf{length \: of \: frame \: needed \: = perimeter \: of \: square \: mirror} \\ \sf{perimeter \: of \: mirror = 4 \times side } \\ \sf{ = 4 \times (30)cm} \\ \sf{ = 120cm} \\ \sf{ = \underline{\underline{1.2m}}}$

ᴛʜᴇ ʟᴇɴɢᴛʜ ᴏғ ғʀᴀᴍᴇ ɴᴇᴇᴅᴇᴅ = 1.2 m

Answer 2

$\huge\tt\fbox{✯Answer✯}$

$\bf\underline\green{Given:}$

• Side of the square mirror = 30 cm

Length of the frame = perimeter of the square m

$\sf\pink{now\:let's\:calculate\:the\:perimeter\:of\:the\:square\:mirror}$

we know,

Perimeter = 4 ×sides

$\bf{⇒4×30}$

$\bf{⇒120 \: cm}$

$\bf{⇒1.2m \: }$

Therefore, the length of the frame should be 1.2 m
