The area of the triangle is 15.75. The height is 9 units.

What is the length of the base?

3.5

Step-by-step explanation:

area of the triangle = 1/2 × base × height

so to find the base of triangle = 2 × area divided by the height

area is given = 15.75

and height = 9

so base = 2 × 15.75 divided by 9

base = 3.5

can i get the link to the assignment?

step-by-step explanation:
