Answer:
PQ = 11
Step-by-step explanation:
Area of trapezium = ½(a + b)h
Where,
Area (A) = 196 m²
a = RS = 17 m
b = PQ
h = PT = 14 m
Let's find PQ. Substitute the known values into the formula:
196 = ½(17 + PQ)*14
196 = (17 + PQ)*7
196 = 119 + 7PQ
196 - 119 = 7PQ
77 = 7PQ
77/7 = 7PQ/7
11 = PQ
PQ = 11
