Question

find the area of each of the following polygons​

Answer 1

Answer:

Here's your answer.

Step-by-step explanation:

Area of triangle= 1/2 × b ×h

= 1/2 × 11 × 60

= 11 × 30

= 330 cm^2

Area of trapezium = 1/2× sum of parallel sides × height

= 1/2 × (61+26) × 18

= 87 × 9

= 783 cm^2

Hope It helps you.

Answer 2

Answer:

1,1118.5 cm²

Step-by-step explanation:

AC² = √AB² + BC²

       = √60² + 11²

       = √3600  + 121

       = √3721   ⇒ 61 cm

Area of  ΔABC = b × h ÷ 2

                         = 11 × 61 ÷ 2

                         = 671 ÷ 2  ⇒ 335.5 cm²

Area of Trapezium ACDE = a + b × h ÷ 2

                                           = 61 + 26 × 18 ÷ 2

                                           = 87 × 18 ÷ 2

                                           = 1566 ÷ 2

                                            = 738 cm²

Area of the Polygon = 335.5 + 783

                                  = 1,118.5
