Answer:
A = 100
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = (a + b)
Now, substitute the values of the height and the bases:
A = (10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100

Hello from MrBillDoesMath!
Answer:
Perimeter = 60
Height = 18/5
Discussion:
The diagonals of a rhombus bisect each other at right angles. So a rhombus can be viewed as the union of 4 congruent right triangles, each with legs (1/2)*18 = 9 and (1/2) *24 = 12. See attachment. This gives a hypotenuse length of 15 so the Perimeter = 4 *c = 60.
The height ( = altitude) of a rhombus is
= area / length of base
= (1/2) ( (18) * 24) /c
= (1/2) ( 18 * 24) / 60
= 18/5
Thank you,
