Ja'Miles designs a sign for a store in the shape of a triangle. His design is 7.5 square feet in area, and the triangle has a height of 2.5 feet. What is the length of the base of his sign? (1 point)
• 0.6 feet
• 6 feet
• 10 feet
• 3 feet
The formula for the area of a triangle is (1/2) x base x height.
Given that the area of the triangle is 7.5 square feet and the height is 2.5 feet, we can plug these values into the formula:
7.5 = (1/2) x base x 2.5
base = 7.5 / (0.5 x 2.5)
base = 7.5 / 1.25
base = 6
Therefore, the length of the base of his sign is 6 feet.
Therefore, the answer is:
• 6 feet
