Question

in a square Park of side 80 metre apart way of width 5 metre is to be constructed find the area of the pathway​

Answer 1

Answer:

1700 m²

Step-by-step explanation:

side of the park = 80m

give path of width 5m is constructed apart, => on the exterior of the park

so, now the side of the square park with path = 80+5+5 m

                                                                            = 90 m

=> area of pathway = area of park with path - area of park alone

                                = (90² - 80²) m²

                                = (90+80)(90-80) m²

                                = (170)(10) m²

                                = 1700 m²
