Question

You allready know i need help my brains to tinyyyyyyyy

Answer 1

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

Step-by-step 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!

Answer 2

Answer: 2.25ft²

Step-by-step explanation: (1/2 x base x height)x2

                                              (1.2 x 3 x 0.75)x2

                                              2.25ft²
