Question

A garden 15meter long and 10meter wide is surrounded by a path 4 meter wide find the area of the path

Answer 1

Length of outer rectangle ( path ) = 15+4+4=23m

Breadth of outer rectangle ( path) =10+4+4=18m

AREA OF OUTER RECTANGLE- AREA OF INNER RECTANGLE

23×18=414msquare

15×10=150msquare

414-150=264msquare ANS

THIS FORMULA IS ONLY APLLIED WHEN PATH IS SURRONDED EXTERNALLY
