Question

3 units

Answer 1

Answer:

Area = 132 Square units

Step-by-step explanation:

Looking at the diagram, the top horizontal chord distance that's missing is calculated as;

21 - (9 + 3) = 9 units

Total distance of top horizontal chord = 9 + 3 = 12 units

Now, formula for area of trapezium is;

Area = ½(a + b)h

Where h is height = 8 units

The parallel sides are a & B.

In this case; a = 12 units

b = 21 units

Thus;

Area = ½(12 + 21)8

Area = 4 × 33

Area = 132 Square units
