Answer:
area of trapezium: 740 cm²
Step-by-step explanation:
[tex]\sf {Area \ of \ trapezium = \frac{1}{2}* (base \ 1 \ + base \ 2) \ * height }[/tex]
Given here:
using the formula:
[tex]\sf {Area \ of \ trapezium = \frac{1}{2}* (base \ 1 \ + base \ 2) \ * height }[/tex]
solve:
[tex]\sf {\frac{1}{2}* (34 \ + 40) \ * 20}[/tex]
[tex]\sf {\frac{1}{2}* (74) \ * 20}[/tex]
[tex]\sf 74 * 10[/tex]
[tex]\sf 740[/tex]
