Question

A Rectangular plot has length 80m breadth 45m.a 4m wide path extends long the inside edge of the plot. find the area of the path?

Answer 1

area of rectangle = 80×45 = 3600m^2
are of rectangle with path = 80+4+4 × 45+4+4
88×53
4664m^2

Area of path = Area of rectangle with path - Are of rectangle
Area of path = 4664-3600
Area of path = 1064m^2

Answer 2

area = l*b*h
$80m \times 45m \times 4m$

so (80m*45m*4m)
(80*45*4)m³
14400m³
