Calculate CDEFtrapezium
pantera1 [17]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

You need to find the length of A F and BC first

Lets call BC --> 'x'

Lets form an equation

9 + 9 + x + x = 28

18 + 2x = 28

- 18

2x = 10

/ 2

x = 5

So now we have the length BC

We can subtract this length from the 11cm to find the vertical height of the trapezium

11 - 5 = 6

Now we have all we need to work it out.

area = (a + b) / 2 x h

area = (5 + 9) / 2 x 6

area = 42 cm^2

Have A Nice Day ❤    

Stay Brainly! ヅ

Benny: 12

Half of 48 is 24, so Benny will have to turn 24.

24 - 12= 12
