Question

find the area of shaded portion.
​

Answer 1

Answer:

first answer

area of shaded region=

area of rectangle+(area of rectangle2 -area of rectangle3)

first, convert metre to centimetre

5m=500cm

7.5m=750cm

area of rectangle=1.5cm×500cm=750cm

area of rectangle2=2cm×750cm=1500cm

area of rectangle3=1.5cm×2cm=3cm

therefore,

area of shaded region=750+(1500-3)

=750+1497=2247 cm
