Question

What is the area of the shaded region in the figure, if it is given that the side of square ABCD is 90 m and the side of square PQRS is 100 m?

• A. $2000m^2$
• B. $1000m^2$
• C. $1900m^2$
• D. $2500m^2$

Answer 1

The correct option is C

$1900m^2$

Given: Side of square ABCD = 90 m

Side of square PQRS = 100 m

Area of the shaded region = Area of square PQRS - Area of square ABCD

$={100}^2-{90}^2$

$=10000-8100$

$=1900m^2$

$\therefore$ Area of the shaded region is $1900m^2$.
