Answer:
3.4
Step-by-step explanation:
This is a rhombus and in any rhombus, the diagonals intersects in the middle and they are perpendicular:
So all 4 triangles are right triangles and the sides are the hypotenuses.
1st) Calculate the sides: hypotenuse² = 3² + 4² = 25, and hypotenuse = 5
The area of each right triangle is (4 x 3)/2 = 6 units²
And the area of the 4 right triangles = 4 x 6 = 24 init²
Answer:
12^3,
Step-by-step explanation:
Answer:
b = 10/3
Step-by-step explanation:
39=1 3/10b would be clearer if rewritten as 39 = (1 3/10)b. We are to solve this for the value of b.
Rewrite the mixed number 1 3/10 as 13/10. Then we have 39 = (13/10)b.
To isolate b, multiply both sides of this equation by 10/13:
10
---- * 39 = b, or b = 10/3
13
