JoJo designed a sign for a store in the shape of the triangle. His design is 7.5 ft.² in area and the triangle has a height of 2.5 feet. What is the length of the base of his sign?
To find the length of the base of the triangle, you can use the formula for the area of a triangle:
Area of a triangle = 1/2 * base * height
7.5 = 1/2 * base * 2.5
Now, solve for the base:
7.5 = 1.25 * base
base = 7.5 / 1.25
base = 6
Therefore, the length of the base of JoJo's sign is 6 feet.
