Question 885801
Hi, I have the following word problem I could really use some help with:
If the length of each side of a square is decreased by 4 in., the perimeter of the new square is 10 in. more than half the perimeter of the original square. What are the dimensions of the original square?
***
let x=length of side of original square
Its perimeter=4x
x-4=length of side of new square
Its perimeter=4(x-4)
..
4(x-4)=4x/2+10
lcd:2
8(x-4)=4x+20
8x-32=4x+20
4x=52
x=13
length of side of original square=13 inches
