Answer 1

Answer:

 b = $\frac{26}{3}$ =$8\frac{2}{3}$ cm

Step-by-step explanation:

Area of triangle= $\frac{1}{2} *b*h$

                  130 =$\frac{1}{2} *b*30$

               130*2 = 30b

               $\frac{130*2}{30}$   =  b

                      b = $\frac{26}{3}$ =$8\frac{2}{3}$ cm

Answer 2

Answer:

Base = 8.67cm

Step-by-step explanation:

Formula of :

area of the triangle = $\frac{1}{2}$ × base × height

Let base be (b)

⇒ 130 (given) = $\frac{1}{2}$ × b (base) × 30 (given)

⇒ 130 = $\frac{1}{2}$ × b × 30

∴ The answer is 8.67 cm
