Question

What is the area of this polygon?

Answer 1

The middle is a square with side length of 12cm

Area of the square = 12 x 12 = 144 cm^2

There are 4 triangles with base of 13cm and height of 8 cm

Area of triangle = 1/2 x base x height

Area = 1/2 x 12 x 8 = 48cm^2 each

48 x 4 = 192 cm^2

Total area = 144 + 192 = 336 cm^2

Answer 2

Answer:

Area of given polygon = 4(1/2 × 8 × 12) + 12²

• 4 × 48 + 144
• 192 + 144
• 336cm²

Hence, The area of the given polygon is 336 sq cm.
