Answer:
1 x ( a + b ) × h
2
1 x ( 9× + 4 + 12× -2) x h
2
1 x ( 13× + 10× ) × h 7x + 8= 15× a squared + b squared is equals to c squared
2 10 x + × = 15×
1 x ( 23x ) x h 100× + × = 225
2 x = 225 - 100
x = 125
x = 11.1803398875
x = 11.2
11.5 x h
11.5 x 11.2
= 128.8 height is 11.2
Step-by-step explanation:
Formula for trapezium half multiplied by the top and the bottom multipliedby height. As u constantly glance at the
question we dont know the height .adjacent plus opposite gives u hypotenuse .
