Question

Find the perimeter.
15 ft
25 ft
if the 25ft is diagonal in a rectangle

Answer 1

P=70ft

Explanation:

25^2-15^2=400
Sqrt400=20

2l+2w=P

40+30=70

Answer 2

Using Pythagorean theorem,
Let c=25 & b=15.
Therefore a=20


Perimeter is 2l+2w, and since a=20&b=15 are the length and width, we can plug that into the formula to get

70 ft
