Answer 1

area of the given polynomial is 425cm^2

Answer 2

Answer....

In the above figure we can see that there r two trapeziums.

Height of the first trapeziums=10cm

Parallel sides of the first trapezium = 20 cm and 30 cm

Area of trapezium=

$\frac{1}{2} \times (sum \: of \: parallel \: sides) \times height \\ = \frac{1}{2} \times (20 + 30) \times 10 \\ = \frac{1}{2} \times 50 \times 10 \\ = 50 \times 5 \\ = 250 {cm}^{2}$

Height of the second trapezium=10cm

Parallel sides of the trapezium=30cm and 5 cm

Area of trapezium=

$\frac{1}{2} \times (sum \: of \: parallel \: sides) \times height \\ = \frac{1}{2} \times (30 + 5) \times 10 \\ = \frac{1}{2} \times 35 \times 10 \\ = 35 \times 10 \\ = 175 {cm}^{2}$

Area of the polygon=Area of first trapezium+Area of second trapezium

={250+175}cm^2

=425cm^2
