Any help on this??
not sure but simple question just never been good at these

Answer 1

159.5mm³

Step-by-step explanation:

What is area?

Area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve this, we can split the shape into two separate shapes. We can do this by thinking of the shape as a square with a triangle attached.

The squares dimensions are 11m and 9m.

An expression you can use to solve for the area of a rectangle and the area of a triangle is:

• (Length × width) = area of a rectangle.

• (Length × width) ÷ 2 = area of a triangle.

To solve for the triangle's width, we can take the total width and subtract that by 9.

• 20 - 9 = 11

So, the triangles dimensions are 11m by 11m.

The equation we can use to solve for the total area is:

• (Area of rectangle + area of triangle)

• (11 × 9) + [(11 × 11)
  `(1)/(2)`]

• (11 × 9) + (121 ×
  `(1)/(2)`)

• (11 × 9) + 60.5

• 99 + 60.5

• 159.5

Therefore, the area of the figure is 159.5m³.
