The area of this trapezium is 180cm?. Work out x.
9cm
13cm
12cm
The diagram is not drawn to scale.

13x • 9 = 12
9/9= 12/9
13x = 1.3
13/13= 1.3/13
X= 0.1
I am not sure but this is what i think

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
