Solving exercise 3 on pages 144 and 145 of Math textbook grade 4 is part of Concentration Practice. Circle the letter preceding the correct answer.
Guidance for solving exercise 3 on pages 144 and 145 of Math textbook grade 4:
Solving method:
- Formula for finding the area of a square: A = a x a (where: a is the side length)
- Formula for finding the area of a rectangle: A = a x b (where: a is the length, b is the width)
- Formula for finding the area of a rhombus: A = (a x b) x 2 (where: a, b are the lengths of the diagonals)
=> After finding the areas of the shapes, we compare them to determine which shape has the largest area.
