I need help how to solve these kind of geometry word question which have something like, an triangle as 3 time less then the length of the othere side. here is two question, i want to use these two different question to work on the other question that I have.
1-If two side of the triangle are equal in length and the third side is 6 inches less than the length of the one of the equal sides, find the length of the side if the perimter is 24 inches. Geometric principle: the perimtere of a triangle is equal to the sum of the lengths of it's side.
2-The permeter of a rectangle is 42 inches and the length is 3 times the width. find it's demensions geoetric principle: the Permeter of the rectangle is P=21+2w
also for numer two, if it say something different like "the length is 3 inches less then the width" what would I do next?
P.s Thanks you in Advance for helping me with two of these long question.!
