and MN IPS. Find the area of the shaded
region in hectares.
S​

Answer 1

Answer:

Area of shaded region=0.5ha

Step-by-step explanation:

PQ=QR=RS=SP=100m

PQ=MN=100m

Area of shaded region

=Area of square-Area of triangle

=(side)²-½×b×h

=(100)²-½×100×100

=10000-50×100

=10000-5000

=5000m²

=0.5ha

Answer 2

Given,

PQRS is a square

Side of the square = 100m

To find,

Area of the shaded region

Solution,

PQ = QR = RS = SP = 100m

PQ = MN = 100m

Area of shaded region = Area of square - Area of the triangle

=(side)² - ½ × b × h

=(100)² -½ × 100 × 100

=10000 - 50 × 100

=10000 - 5000

=5000m²

Thus, the area of the shaded region is 5000m²
