total area -the interior area will be the answer
Answer:
Step-by-step explanation:
Area of the shaded portion along the length:
Length = 48m
area of the shaded portion along the length=48 x 3
= 108m2
Total area of two shaded portion along the length =
108 x 2
= 216 m2
area of shaded portion along the breadth= 48 x 3
=144m2
total area of two shaded portion along the breadth = 144 x 2
=288m2
(a) Total area of the four shaded portion = area of the shaded portion find above - common area
= (216+288) - 4x(3x3)
=504 - 36
=468m2
Total area of the four shaded equal = 468 m2
(b) 100sqm = 160rs
1sqm = 160÷100
1sqm = 1.6rs
Cost of flooring = 1.6x468
748.8m2
The cost of flooring of the shaded area = 748.8m2
And the area of shaded portion = 468m2.
