Answer:
35.75 meters squared
Step-by-step explanation:
The area of a trapezoid is denoted by: 
, where b_1 and b_2 are the bases and h is the height.
Here, the two bases are 7 1/2 and 5.5 meters and the height is 5.5. So, just plug in the values:
7 1/2 is the same as 7.5: 
Thus, the area is 35.75 meters squared.
Hope this helps!
Answer:
<u>3/5</u>
Step-by-step explanation:
= 2/3 + 2/5 - 7/15
= 10/15 + 6/15 - 7/15
= 9/15
= <u>3/5</u>
Answer:
y = 4 (9)x

To find out if a triangle is a right triangle, you can use the Pythagorean theorem(which can only be used for right triangles):
a² + b² = c² (c is the hypotenuse or the longest side) And you can plug in the side lengths into this equation. If they are the same number on both sides, it is a right triangle, if they are different numbers it is not a right triangle.
6.) a² + b² = c²
(4√3)² + (11)² = (13)²
(16(3)) + 121 = 169
48 + 121 = 169
169 = 169 It IS a right triangle
7.) a² + b² = c²
(5)² + (2√14)² = (9)²
25 + (4(14)) = 81
25 + 56 = 81
81 = 81 It IS a right triangle
8.) a² + b² = c²
(6)² + (√49)² = (√82)²
36 + 49 = 82
85 = 82 It is NOT a right triangle
9.) a² + b² = c²
(13)² + (2√39)² = (16)²
169 + (4(39)) = 256
169 + 156 = 256
325 = 256 It is NOT a right triangle
