The perimeter of the square is twice theperimeter of the triangle. Find the length of a side of thetriangle. 17) The length of a rectangle is twice the length of a side ofa square and the width of the rectangle is 1 mm less than the sideof the square. If the perimeter of the rectangle is 8 mm more thanthe perimeter of the square, find the length of a side of thesquare. 18) An architect wants to design a rectangular room so thatits length is 8 meters more than 56 meters.

Explanation / Answer

16.Well I'll turn it into a equation where L= length oftriangle. 6L=4L+28 2L=28 L=14 17..I'll do the same thing as question one where L=length of aside of the square. 6L-6=4L 2L=6 L=3 18.Well if its length is 8+56=64 and the least whole is 1 sothe length is 64 and the width is 1
