Question

find the areas of following polygons. please do 2nd and 4rth ​

Answer 1

Answer:

2) 214.28 cm²

4) 17.5 cm²

Step-by-step explanation:

Question 2:

The figure is made up of a regular hexagon and a rectangle.

Find the area of the hexagon:

$\text {Area of hexagon = } \dfrac{3\sqrt{3} }{2} a^2$

$\text {Area of hexagon = } \dfrac{3\sqrt{3} }{2} (8)^2$

$\text {Area of hexagon = } 166.28 \text{ cm}^2$

Find the area of the rectangle:

Area of rectangle = Length x Breadth

Area of rectangle = 4 x 12

Area of rectangle = 48 cm²

Find the total area of the figure:

Total area = 166.28 + 48 = 214.28 cm²

Question 4:

The figure is made up of a rectangle with a missing triangle.

Find the area of the rectangle:

Area of rectangle = Length x Breadth

Area of rectangle = 6 x 3

Area of rectangle = 18 cm²

Find the area of the missing triangle:

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x (3 - 2) x (6 - 5)

Area of triangle = 1/2 x 1 x 1

Area of triangle - 0.5 cm²

Find the area of the figure:

Area of the figure = 18 - 0.5 = 17.5 cm²

Answer 2

Answer:

use area of trepizium and in first

and area of rectangle

in second use area of rectangle and subtract area kf triangle
