polygon.
area
of
the
following​

Answer 1

Step-by-step explanation:

area of the trapezium =1/2×10×(10 +30) cm^2

=200cm^2

area of the triangle=

(1/2×5×30)cm^2

=75cm^2

total area of the polygon=

(200+75)cm^2

275cm^2

Answer 2

Answer:

1) triangle Area = bh/2=10x10/2=50

2) square = a2 = 10x10=100

3) triangle = bh/2=10x10/2=50

4) triangle = bh/2 = 30x5/2=75
