Question

The side of an equilateral triangle is 2.5,what is the area and perimeter of rectangle

Answer 1

I think you asked me to find the area and perimeter of the triangle.If so...
perimeter of an equilateral triangle is 3a
a=2.5
therefore 3a=3×2.5
=7.5
the perimeter of the triangle is 7.5
area =√3/4×a^2
=√3/4×(2.5)^2
=√3/4×6.25
then the answer will be 2.7063 and so on
so you can write 2.7
