If rectangle : triangle = 15 : 4,
Then rectangle area = 15 units
Triangle area = 4 units
shaded area = 15 units - 4 units
= 11 units
11 units = 136.4 cm²
1 unit = 136.4 cm² ÷ 11 = 12.4 cm²
Area of triangle
= 4 units
= 12.4 cm² x 4
= 49.6 cm²
Then rectangle area = 15 units
Triangle area = 4 units
shaded area = 15 units - 4 units
= 11 units
11 units = 136.4 cm²
1 unit = 136.4 cm² ÷ 11 = 12.4 cm²
Area of triangle
= 4 units
= 12.4 cm² x 4
= 49.6 cm²
