Answer:
x = 3 + 2 sqrt3 Or 3 - 2 sqrt 3
Step-by-step explanation:
10/14 = 5/7 in simplest form
Area of Trapezoid is = 1/2 x height x (base1 + base2)
Here, Area = 98, base1 = 8, base2 = 20 and height = unknown (x)
So, 1/2 x height x (8+20) = 98
==> 1/2 x height x 28 = 98
==> height x 14 = 98
==> height = 98/14
==> height = 7 units
So, the final answer is --> the value of x = 7 units
You have to subtract 48 minus 14 and you get 34. Then split 34 and you get 17 which is the width.
Answer: 49 cm² and 16 cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter os 4:7, then the areas are in the following ratio:

2. You know that the sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:

3. The area of the smaller triangle is:
