Answer 1

Answer:10 sq cm

Step-by-step explanation:

area of rectangle= l*b

= 5*4=20sq.cm

Now area of shaded region= area of rectangle ( l=5;b=1cm)+area of right angled triangle(b= 2cm;h=5cm)

Therefore (5*1)+(1/2*2*5)

=10 sq. cm

Answer 2

Answer:area of shaded region=area of rectangle-area of trapezeium

Step-by-step explanation:

Area of rectangle=l×b

=5×4

=20cm2

Area of trapezeium =1/2×(sum of parallel sides)×(height)

Therefore,

1/2×(1+3)×5

=1/2×4×5

=10cm2

Hence,area of shaded region =20cm2-10cm2

=10cm2
