Question

Daisy is making an abstract painting with two triangles. The dimensions of the painting are shown below:

Answer 1

Triangle area formula= bh/2

Blue triangle:
10*12/2= 60

Orange triangle:
8*10/2= 40

Add the values: 40+60= 100 in^2

Final answer: 100 in^2

Answer 2

Answer:

The total area of the two triangles is 100 square inches.

Step-by-step explanation:

We know that the area of triangle is given by the formula:

$Area=\dfrac{1}{2}bh$

where b is the base of the triangle and h is the height of the triangle.

The triangle which is shaded blue:

Has a base(b)=12 in.

and height(h)=10 in.

Hence, Area of blue triangle is:

$Area=\dfrac{1}{2}\times 12\times 10\\\\\\Area=60\ square\ in.$

and the Triangle which is shaded orange has base(b)=8 in.

and Height(h)=10 in.

Hence, the area of orange shaded triangle is:

$Area=\dfrac{1}{2}\times 8\times 10\\\\\\Area=40\ square\ in.$

Hence, the total area of two triangle is:

    60+40=100 square inches.
