Answer» In a rectangular park having a length of 45m and width of 18m, four corners of 3² m are demarcated for planting trees.⠀As there are four SQUARE corners of 3² m are demarcated for planting trees. ⠀→ Area of four square corners = 4 × 3²→ Area of four square corners = 4 × 9→ Area of four square corners = 36 m²⠀Now, we have length and breadth of the park i.e., Length = 45mBreadth = 18m⠀→ Area of park = Length × Breadth→ Area of park = 45 × 18→ Area of park = 810 m²⠀Since we have to find the area of park that can be used by CHILDREN for playing.The REQUIRED area will be the area EXCEPT the four corners.⠀•°• Required area = Area of park - Area of four corners⠀→ Required area = 810 - 18→ Required area = 792 m²⠀Hence,Area of park that can be used by children for playing is 792m².
