Can you find the trapezoid’s perimeter

I’m marking branliest

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 .
