Answer:
189 cm²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = × product of diagonals
= × 18 × 21 = 9 × 21 = 189 cm²
Rewrite the equation by completing the square x^2+10x+16=0

the volume of the oblique pyramid is 16 cubic units
<h3>How to determine the volume</h3>The formula for finding the volume of a oblique pyramid is given as;
Volume = × base area/ height
Where
base area = area of a right triangle
From the lengths of the triangle given, we can deduce that the opposite side is 24unit and the adjacent side or the base is 10 unit
let's put in the values to the formula
Base area = 10 × 24
Base area = 240 units
height = 5 units
Since we have both the height and the base area, let's find the volume
Volume = ×
Volume = ×
Find the division
Volume = 16 cubic units
Thus, the volume of the oblique pyramid is 16 cubic units
