Respuesta :

hiya!

x is going to work out to 25.

———————————————

so first put the numbers into the equation you’ve been given.

pressure is 3, force is 1500 so 3=1500/area

then rearrange this equation so that you’re finding area.

area=1500/3

and 1500/3 gives you 500.
so 500 is the area.

area is length multiplied by width, so 20 multiplied by x.
total/width will give length, so 500/20 will give x.
500/20=25

so x is 25.
