Answer:
A. 74 cm
Step-by-step explanation:
First, we break the rhombus down into similar shapes,
The area of 2 triangles = The area of a square
So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,
10 multiplied by 5 =50
Thats the area of rectangle 1
Rectangle 2
3 multiplied by 6 = 18
Triangle
4 times 3 divided by 2 = 6
Thus
6 + 18 + 50 = 74

Answer: 1. False
2. True
3. True
4.False
Step-by-step explanation:
1. False, because 6 is a multiple of 3 but 6 is not an odd number.
2. True, all even numbers are multiple of 2, and thus divisible by 2. Any number that is divisible by 2 must be a multiple of 2. hence,the given biconditional statement in true.
3. True, all multiples of 5 has 0 or 5 in the ones place.
Thus the given biconditional statement is true.
4.False, because 6 is not a multiple of 4 but 6 is not a prime number.
