height = 12 cm

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the parallel bases.

Here A = 120, a = 6 and b = 14 , thus

$\frac{1}{2}$ h (6 + 14) = 120

$\frac{1}{2}$ h × 20 = 120

10h = 120 ( divide both sides by 10 )

h = 12 cm

6x-22+ 8x+34+ 6x-22+8x+34=360
20x+24=360
20x=360-24
20x=336
x=336:20
x=16,8

R=8 x 16,8 + 34
= 134,4 +34
=168,4
