Question

3. What length of wire is neeed to make a triangle of sides 10
centimetres each? To make a square of side 10 centimetres?

i. What is the total length needed to make 5 such triangles
and 6 such squares?​

Answer 1

$length \: of \: wire \: needed \: to \: make \: triangle \: of \: side \: 10cm = 10 \times 3$

$= 30cm$

$total \: length \: of \: wire \: needed \: to \: make \: such \: 5 \: triangles = 5 \times 30$

$= 150cm \: or \: 1.5m$

$length \: of \: wire \: needed \: to \: make \: square \: of \: side \: 10cm = 10 \times 4$

$= 40cm$

$total \: length \: of \: wire \: needed \: to \: make \: such \: 6 \: squares = 40 \times 6$

$= 240cm \: or \: 2.4m$
