Answer: Two ways to do this, you can find the area of the rectangle and subtract the 4 triangles or find the area of 4 triangles.
B: 2.25 ft2
Explanation:
Well, I will first start by finding the area of the top 2 triangles.
The equation to a triangle is:
A = 1/2 × l × w
I will replace now the variables:
1/2 × 1 × 0.75 = 0.375
One triangle is 0.375, now I have to find the area of two triangles.
0.375 × 2 = 0.75
Now I will do the bottom 2 triangles.
The equation to a triangle is:
A = 1/2 × l × w
I will replace now the variables:
1/2 × 2 × 0.75 = 0.75
One triangle is 0.75, now I have to find the area of two triangles.
0.75 × 2 = 1.5
Now time to add it up.
1.5 + 0.75 = 2.25
So the final answer is B: 2.25 ft2
Hope this helps you!
