Answer 1

Answer:

Question :

Above

Answer :

$3) perimeter \: = \: 4a \\ \\ 36 = 4a \\ \\ a = \frac{36}{4} \\ \\ = 9 \\ \\ side \: = 9$

$4) \: dis = 64 \: time \: = 2 \\ \\ \\ speed \: = \frac{distance}{time} \\ \\ = \frac{64}{2} \\ \\ = 32 \: km \: per \: hour$

$5) \: remaining \: length \: \\ \\ = 80.82 - 9.76 = 71.06 \: m$

Thank you !

Answer 2

Step-by-step explanation:

3. let x be the side of the square park

given perimeter = 36 m

$perimeter \: of \: square \: =(side)^2 \\ {x}^{2} = 36 \\ x = \sqrt{36} \\ x = 6$

the side of square park is 6m .

4. as we know that

$speed = \frac{distance }{time} \\ speed = \frac{64 \: km}{2 \: hr} \\ speed = 32 \: \frac{{km}}{{ hr} }$

$5. \\ 80.82 \: m \\ - \:09.76 \: m \\ - - - - - \\ 71.06 \: m \\ - - - - -$
