The answer to your question is 92.4 cm²

Step-by-step explanation:

Data

Side of a square = 6 units

Longest side of a rhombus = 10 units

Process

1.- Calculate the area of the square

Area = 6 x 6 = 36 u²

2.- Calculate the area of the rhombus

-Calculate the length of the short diagonal

     6² = x² + x²

     6² = 2x²

     36 = 2x²

     18 = x²

     x = √18

-Short diagonal

     x = 2√18

-Calculate the length of the long diagonal

    10² = (√18)² + b²

    b² = 100 - 18

    b² = 82

    b = √82

-Length of the long diagonal

    d = √82 + √18

-Area of the rhombus

 Area = (√82 + √18)(2√18) / 2

 Area = (√82 + √18)(√18)

3.- Calculate the total area

Total area = (√82 + √18)(√18) + 36

-Simplification

Total area = (13.298)(4.243) + 36

Total area = 56.418 + 36

Total area = 92.4 cm²
