Question

A wire is first bent into the shape of a range Each side of the triangle is 16 cm long. Then the wire is unbent and reshaped into a square. what is the length of a side of the square

Answer 1

it was first bent to a triangle of each length 16 cm.

total length = 16 + 16 + 16 = 48 cm

The wire is resghaped into a square. Therefore

perimeter of the square = 4l

perimeter = 48 cm

`\begin{gathered} 48=4l \\ l=(48)/(4) \\ l=12\text{ cm} \end{gathered}`
