Question

Help, what is the area of this figure? (Don’t write a big explanation!!, i really need this quick, a picture or just numbers u used is fine)

Answer 1

Answer:

146 m²

Area of triangle:

• 1/2 * base * height

• 1/2 * 16 * 7

• 56 m²

Area of upper rectangle:

• Length * Width

• 8 * 9

• 72 m²

Area of bottom rectangle:

• Length * Width

• 6 * 3

• 18 m²

Total area:

• 18 m² + 72 m² + 56 m²

• 146 m²

Answer 2

Answer:

146 m²

Step-by-step explanation:

Divide the figure into a triangle and 2 rectangles (see attached diagram)

Formulae

• Area of a triangle = 1/2 x base x height
• Area of a rectangle = width x length

Triangle 1

⇒ area = 1/2 x 16 x (6 + 9 - 4 - 4)

            = 1/2 x 16 x 7

            = 56 m²

Rectangle 2

⇒ area = 3 x (6 + 9)

            = 3 x 15

            = 45 m²

Rectangle 3

⇒ area = 5 x 9

            = 45 m²

Total area

⇒ Total area = triangle 1 + rectangle 2 + rectangle 3

                      = 56 + 45 + 45

                      = 146 m²
