Question

Can some one explain to me how I do it step by step to understand and with answer what is the area and perimeter and type please

Answer 1

This is a square. because the lengths and the widths are equal. I mean, all four sides are equal.


the area of a square is the square of a side
${s}^{2} = {5.4}^{2} = 29.16$

and the perimeter of a square is a side multiplied by 4
$4s = 4 \times 5.4 = 21.6$




hope this helps


good luck
