Question

Someone help me please

Answer 1

The answer is 2.5 or b/5

Answer 2

Answer:

2.5 or 5/2

Step-by-step explanation:

The formula for the area of a triangle is \dfrac{bh}{2}, where b represents the length of the base and h represents the length of the height. With this in mind, you can set up the following equation:

$\dfrac{15}{8}=\dfrac{1.5b}{2}$

$\dfrac{15}{4}=1.5b$

b=2.5 or $\frac{5}{2}$

Hope this helps!
