The formula for finding the area of a trapezoid is: sum of bases*height*1/2
By plugging in the information that we already have, we know: (119+65)*height*1/2=5658
184*1/2*height=5658
92*height=5658
height=61.5cm.
Check:
119+65=184
184*61.5=11316
11316*1/2=5658

Answer:
_20___ × (-1/2) × __2__ = -20
8 x (-1/2) x 5= -20
Step-by-step explanation:
Hope I helped
We would have
a + b = 360
a - 40 = b, so we solve as follows:
360-40=320,
320/2 = 160,
160 + 40 = 200.
Check: 200+160 = 360, so
200 is your answer.
Hope this helps and have a nice day:)
