For this question, find the area of each individual figure and then add all of them together.
Let's start with the triangles. To find the area of a triangle, use the formula A =
bh (b = base and h = height).
A =bh
A =(30)(40)
A =(1200)
A =
A = 600m²
There are 4 triangles, so multiply the area of one triangle by 4 to find the area of all 4 triangles.
(600)(4) = 2400m²
Now we can find the area of the square. To find the area of a square, simply multiply the length x width (or square one side).
A = l x w
A = (30)(30)
A = 900m²
Add together the area of the triangles and the area of the square to get the total area:
2400 + 900 = 3300m²
