The figure on the top left is a triangle with base 11 and height 8, for an area of
Immediately below, we have a rectangle with dimensions 11 and 9, for an area of
Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height
Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of
Sum these areas and you'll get the total area
9514 1404 393
Answer:
The triangle is not acute because 2² + 4² < 5²
Step-by-step explanation:
The square of the hypotenuse of a right triangle with the given short sides would be 2² +4² = 20. So, that hypotenuse would be √20, about 4.47. The long side of this triangle is longer than that, so the angle opposite is larger than 90°. The triangle with sides 2, 4, 5 is an obtuse triangle.
The triangle is not acute because 2² + 4² < 5²
