Answer:

17

Step-by-step explanation:

1/ 2bh=34

b=?,h=4

2b=34

b=17

Answer 2

The value of base is 17 cm.

Step-by-step explanation:

The area of triangle PQR is, $A=34\ cm^2$

Height of the triangle, h = 4 cm

It is required to find the value of QR. It must be the base of triangle. The area of triangle is given by :

$A=\dfrac{1}{2}\times \text{base}\times \text{height}\\\\b=\dfrac{2A}{h}\\\\b=\dfrac{2\times 34}{4}\\\\b=17\ cm$

So, the value of base is 17 cm.
