Calculate the size of Camp A (Rounded to full ha) given dimensions a=1124m, b=1246m, c=400m, d=550m, e=400m, f=754m. Camp A is a trapezoid with height a, top base c, and bottom base d.

Here are the calculations for the minifarm:

Step 1: Identify the given dimensions.

• $a = 1124 \text{ m}$
• $b = 1246 \text{ m}$
• $c = 400 \text{ m}$
• $d = 550 \text{ m}$
• $e = 400 \text{ m}$
• $f = 754 \text{ m}$

11.1 Calculate the size of Camp A (Rounded to full ha)
Camp A is a trapezoid with height $a$, top base $c$, and bottom base $d$.
The formula for the area of a trapezoid is $A =
