The correct answer is: 1/2(7-3)+(7-6)
To find the area of the figure, we need to add the areas of the two triangles. The area of a triangle is calculated by multiplying the base by the height and dividing by two.
The base of the first triangle is 7 cm and the height is 7 cm. Therefore, the area of the first triangle is:
Area of first triangle = 1/2 * 7 cm * 7 cm = 24.5 cm²
The base of the second triangle is 7 cm and the height is 6 cm. Therefore, the area of the second triangle is:
Area of second triangle = 1/2 * 7 cm * 6 cm = 21 cm²
Therefore, the total area of the figure is:
Area of figure = Area of first triangle + Area of second triangle
Area of figure = 24.5 cm² + 21 cm²
Area of figure = 45.5 cm²
The only expression that matches the answer is:
1/2(7-3)+(7-6)
Therefore, the correct answer is: 1/2(7-3)+(7-6)
