Question

determine the area of the following polygons
i will mark the brainliest who gives me the correct answer first​

Answer 1

Step-by-step explanation:

Part 1 :

Length of rectangle = 25cm

Breadth of rectangle= 12 cm

Area of Rectangle = Length x Breadth

= 12 x 25

= 300cm2

Part 2 :

Length of rectangle = 4cm

breadth of Rectangle = 12-4 = 8cm

Area of Rectangle = Length x Breadth

= 8 x 4

= 32cm2

Part 3 :

Base of triangle = 12cm

Height of triangle = 5cm

Area of triangle = 1/2 x base x height

= 1/2 x 12 x 5

= 30cm2

Part 4 :

base of triangle = 8cm

Height of triangle = 2cm

Area of Triangle = 1/2 x base x height

= 1/2 x 8 x 2

= 8cm2

Part 5 :

Total Area of the figure = 300+32+30+8

= 370cm2

Answer 2

Step-by-step explanation:

area of traingle ( blue tick ) = 1

--- b x h

2

b = 12/2

b = 6 cm

h = 5 cm

Area = 1

--- 6 x 5

2

Area = 3 x 5

Area = 15cm²

Area of both (blue tick) traingle = 15cm² x 2

= 30cm²

Area of rectangle (yellow tick ) = l x b

l = 4 cm

b = 12- 4 = 8cm

Area = 4 x 8

= 32cm²

b = 8cm

h = 2cm

Area of ( orange tick ) traingle = 1

--- 8 x 2

2

Area = 8cm²

Area of both traingle = 16cm²

l = 25cm

b = 12 cm

Area of ( green tick ) rectangle = 25 x 12

Area = 300cm²

Total Area of figure = 30cm² + 16cm² + 32cm² +

300cm²

Total area = 378cm²
