18 units^2

Step-by-step explanation:

There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.

Answer 2

Answer:

A = 18 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases )

Here h= 3,  b₁ = 3 and b₂ = 9 , then

A = $\frac{1}{2}$ × 3 × (3 + 9)

   = 1.5 × 12

   = 18 cm²
