There are several numbers on the image: 40, 24, 7, 32, 25. There is also a handwritten number 7. The image shows a triangle with an altitude drawn to the base. The altitude divides the base into two segments, one of length 7 and the other of length 32. The altitude has a length of 24. The two non-base sides of the triangle have lengths 40 and 25. Can you calculate the area of the triangle using the given information?

Analysis:

• The image depicts a triangle with an altitude. We are given the lengths of the sides and the altitude.
• We have a large triangle with sides 40 and 25, and base 32 + 7 = 39.
• The altitude of length 24 divides the base into segments of length 7 and 32.
• Let's check if the given values are consistent using the Pythagorean theorem on the two smaller right-angled triangles formed by the altitude.
• For the left triangle: $$7^2 + 24^2 = 49 + 576 = 625$$. The hypotenuse is $$\sqrt{625} = 25$$. This matches the given side length of 25.
• For the right triangle: $$32^2 + 24^2 = 1024 + 576 = 1600$$. The hypotenuse is $$\sqrt{1600} = 40$$. This matches the given side length of 40.
• The given values are consistent.

Calculation of the Area:

• The area of a triangle can be calculated using the formula: Area = (1/2) * base * height.
• In this case, the base of the large triangle is $$32 + 7 = 39$$.
• The height (altitude) is 24.
• Area = (1/2) * 39 * 24
• Area = 39 * 12
• Area = 468
