Question

What is the area of the triangle below?

Answer 1

Answer: 10

Step-by-step explanation:I like using this method:

Put a square which covers this triangle

Find the area of the rectangle which is 20

Half it which is 10

Now you have the area which is 10

Answer 2

Answer: The other answer is incorrect!

Step-by-step explanation:

An easier way is just imagine it being straight and not slanted. Counting the base its 3blocks and counting from the highest point all the way to the base its 4 blocks. Base=3 blocks and height=4 blocks. Substituting into the tirangle area formula which is b(h)/2 (base times height divided by 2).

You have 3x4=12.

Then 12/2=6 blocks

Therefore the area of the given triangle is 6 blocks squared (din)t forget the square).

The other answer is incorrect because this triangle is not half of this rectangle and in this question it’s just a grid (we have to use the grid)!

Trust me I know this.

Hope this helps!
