Guidance for solving exercise 2 on pages 143 and 144 in the Grade 4 Mathematics textbook

Problem:
A rhombus-shaped piece of glass has diagonals measuring 14cm and 10cm. Calculate the area of this piece of glass.

Solution Method:
To determine the area of that rhombus-shaped glass piece, multiply the lengths of its diagonals and then divide by 2. 

Answer:
The area of the rhombus-shaped glass piece is:
           (14 x 10) : 2 = 70 (cm²)
                     Final Answer: 70 cm²
