You can use the pythagoras theorem.

20^2=5^2+x^2

x^2=400-25
x^2=375

x = 19.36

20-19.36=0.64 feet

The answer is 0.64 feet :)

Can someone please help me with this please

A 40 x 110 rectangle has an area of 4400 sq. ft.

The horse has a 14 ft lead. That makes 14 ft. the radius that the horse can cover.

The formula for the area of a circle is r^2 * PI ( radius squared * 3.14 ).

So the horse can't get to 4400 - ( 14 * 14 * 3.14 ) sq. ft.
