Question

if the area of square is 100 sq cm and it's perimeter is same as the perimeter of an equilateral triangle,what is the length of each side of the triangle​

Answer 1

the formula. for area of a square is =s²

so area of a square =100.

suicide of the square =10 cm

perimeter of the square= 4s

perimeter of a square is 40 cm

then the perimeter of equilateral triangle is also 40 cm

the formula of perimeter of equilateral triangle is sum of all sides

so sum of all sides =40 cm

s+s+s=40

3s=40

s=40/3

s=13.33

so the side of the equilateral triangle is 13.33 cm

Answer 2

answer

perimeter = sum of all length of triangle

perimeter = 3a {a=side of triangle}

45=3a

45/3=a

15=a
