Answer:
4√3
Step-by-step explanation:
This is a right triangle. When two sides are given in a right triangle, we need to use the Pythagorean Theorem to solve for the third side.
Pythagorean Theorem: a² + b² = c²
The a here is 11, while the b is x. The c is always the hypotenuse (the longest side), which is 13.
Now we substitute:
11² + x² = 13²
121 + x² = 169
-121 -121
x² = 48
√x² = √48
x = √48 <-- We can simplify that.
√48 = 12 * 4 = 3 * 4 * 4 = 4√3
(6 x 2)( 49/7) + 5 =
(12)(7) + 5 =
84 + 5 =
89
89 is your answer

8.) Area= 22 squared, Perimeter= 26
9.) Area= 44 squared, Perimeter= 30
we know that the square, 4 equal sides, has a perimeter of 24, meaning each sides is simply 24 ÷ 4 = 6, since the area of a square is simply the side², that means the area of the square is 6² or just 36. We also know that the the trapezium has double the area of the square, namely 2*36 = 72, Check the picture below.
