Answer:
398 ft²
Step-by-step explanation:
Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.
Triangle area = 1/2·bh
Rectangle area = bh
___
So, the <em>first triangle</em> has an area of ...
1/2·(20 ft)(20 ft) = 200 ft²
The <em>second triangle</em> has an area of ...
1/2·(6 ft)(6 ft) = 18 ft²
The <em>rectangle</em> has an area of ...
(30 ft)(6 ft) = 180 ft²
And the area total is ...
200 ft² +18 ft² +180 ft² = 398 ft²
Answer: 70 square centimeters.
Explanation: The area of a parallelogram is base times height.
Because the parallelograms are congruent, we can do 4*(3.5*5), which equals 70 square centimeters.
Answer:
True
Step-by-step explanation:
All equiangular triangles are similar.
That graph seems to be complementary since both angles sum up to be 180 degrees.
