Answer:
Step-by-step explanation:
From the figure attached,
Four rectangles have been formed with different dimensions.
Area of the rectangle with the dimensions = 50 unit by 20 unit
Area of the rectangle = 50×20 = 1000 unit²
Area of the rectangle with the dimensions = 8 unit by 20 unit
Area of the rectangle = 8×20 = 160 unit²
Area of the rectangle with the dimensions = 50 unit by 9 unit
Area of the rectangle = 50×9 = 450 unit²
Area of the rectangle with the dimensions = 8 unit by 9 unit
Area of the rectangle = 8×9 = 72 unit²
Total area of the big rectangle = 1000 + 160 + 450 + 72
= 1682
Therefore, 58×29 = 1682
