Answer:
Step-by-step explanation:
Area of the trapezoid = area of rectangle + 2 * area of triangle
Area of a triangle = 1/2 bh
= 1/2 * 13 * 7
= 45.5 units²
Area of a rectangle = L × B
= 15 × 13
= 195 units²
Area of the trapezoid = [195 + 2 * (45.5)]
= 195 + 91
= 286 units²
Area of a circe = Pi x radius^2
Answer:
17

Step-by-step explanation:
If the original number is ab it has a value of
10a+b when it is reversed it will have a value of 10b-a
10b+a-10a-b is the differences which is equal to
9b-9a
So the numbers must be divisible by 9
