Question

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

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

Answer 1

The correct option is A

$1900m^2$

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 $1900m^2$.
