Answer:

28 yards

Step-by-step explanation:

this is a right angled triangle

this question will be solved by Pythagoras theorem

which states square of hypotenuse=square of legs

so 35= 21sqr+b sqr

1225=441+b sqr

b sqr= 1225-441

b sqr=784

b= sqr root of 784

= 28 yards

perimeter=1/2multiplied to base to height

=(21*35)/2

= 367.5
