Simple Equation in One Variable ( + some Geometry)
Hi there guys!
I've a problem solving this Linear Equations question.
Alright, I drew the Rough Sketch and all... but I don't know how to proceed after that.
ABCD is a rectangle with sides 36cm and 90cm. P is a point on BC, which is one of the longer sides, such that PA = 2PD.
The length of PB is-
a) 80cm b)18cm c)72cm d)64cm
I took the areas of PAD and (PAB + CDP) and the 2 sides of the equation but this way
all the values get cancelled out and you get 1=1. I couldn't really figure out how
Pythagorean Theorem would solve the problem either.
Any advice will be highly appreciated
