Answer:
0.54
Step-by-step explanation:
Area of rhombus = 1/2(product of the diagonals)
A=1/2(1.2×0.9)
A=1/2(1.08)
A=0.54cm² or m² or mm² and so on
Answer:
5/14
Step-by-step explanation:
<h3>Answer:</h3>
15.36 cm
<h3>Explanation:</h3>
The Pythagorean theorem tells you ...
... AC² = AB² + BC² . . . . . relation for face diagonal
... AD² = AC² + CD² . . . . . relation for space diagonal
Subsituting the expression for AC² given by the first equation, the second equaiton becomes ...
... AD² = AB² + BC² + CD²
... AD² = (100 cm²) + (100 cm²) + (36 cm²) = 236 cm²
Taking the square root, we have ...
... AD = √236 cm = 2√59 cm
... AD ≈ 15.36 cm
