Answer:

150cm²

Step-by-step explanation:

area of trapezium=1/2h(a+b)

=1/2×20(7+8)

=10(15)

=150 cm²

Answer:

The area of the trapezium is

150 cm²

Step-by-step explanation:

The area of a trapezium is given by

[tex]Area = \frac{1}{2} (a + b) \times h[/tex]

where

h is the height

a and b are the parallel sides of the trapezium

From the question

h = 20cm

a = 7cm

b = 8 cm

Substitute the values into the above formula

We have

[tex]Area = \frac{1}{2} (7 + 8) \times 20[/tex]

[tex]Area = \frac{1}{2} \times 15 \times 20[/tex]

[tex]Area = 15 \times 10[/tex]

We have the final answer as

Area = 150 cm²

Hope this helps you
