Question

what is the side and perimeter of a square with area 169 cm square​

Answer 1

Given ,

Area of square = 169 cm²

We know that , the area of square is given by

$\sf \underline{\fbox{ \fbox{Area \: of \: square = {(side)}^{2} }}}$

Substitute the values , we obtain

$\sf \hookrightarrow 169 = {(side)}^{2} \\ \\ \sf \hookrightarrow side = \sqrt{169} \\ \\ \sf \hookrightarrow side = 13 \: \: cm$

Now , the perimeter of square is given by

$\large \fbox{ \sf Perimeter \: of \: square =4 \times side }$

Substitute the value , we get

$\sf \hookrightarrow Perimeter = 4 \times 13 \\ \\\sf \hookrightarrow Perimeter = 52 \: \: cm$

Hence , the side and perimeter of square are 13 cm and 52 cm

Answer 2

Answer

13 cm is the side and the perimeter is 52 cm...
