Question

A square park has a pathway on its inside periphery. The side of the park is 1250m long. If the pathway is 2.5 m wide, find the surface area of the pathway.​

Answer 1

Answer:

area of outer = 1250×1250

=1562500

side of inner = 1250-2.5-2.5

=1245

area of inner =1245×1245

= 1550025

area of pathway =1562500 - 1550025

= 12475

Answer 2

Answer:

hey what's up dude

Step-by-step explanation:

$outer \: area \: \: = 1250 \times 0250 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1562500 \\ inner \: side \: = \: 1250 - 2.5 - 2.5 \\= 1245 \\ area \: of \: inner side\: = \: 1245 \times 1245 \\ =1550025 \\ area \: of \: pathway \: = \: 1562500 - 1550025 \\ = 12475$
