A square has an area of 9 sq.m and has a perimeter which is equal to the
perimeter of an equilateral triangle. What is the area of the equilateral triangle?
since 9=3^2 that means each side is 3m and thus the perimeter being 12m and the area of a triangle is half times base times height which means 12 times half equals 6 times 12 which equals 72 therefore ur andwer would be 72 square metres
