Question

Just look at the picture

Answer 1

perimeter = 84 feet

Explanation:

using Pythagoras' identity in the right triangle to find a

a² + 35² = 37²

a² + 1225 = 1369 ( subtract 1225 from both sides )

a² = 144 ( take square root of both sides )

a =
`√(144)` = 12

then

perimeter = 35 + 37 + 12 = 84 feet
