Question

Iam building a building 20ft by 28 ft need to know diagonal measurement?

Answer 1

34.409301068170507086917894140199

Lol.  Pythagorean theorem- A^2 + B^2 = C^2

Answer 2

a2+b2=c2.

20`2+28`2=c2.

400+784=c2.

1184=c2

34.41 feet.

Pythagorean Theorem.

Answer 3

Pythagorean theory:

a (squared)+ b(squared)= c(squared)

28(squared) + 20(squared)= c (squared)

784 + 400= c(squared) or 1184= c (squared)

thus, the squared root of 1184 = c

c= 34.4 ft
