Question

The owner wants to make a board for his new restaurant. He purchased a steel sheet of equilateral triangle shape for the board banner. Perimeter of the sheet is 180m. Now calculate the area of white sheets which he will stick on that board. (Using Heron's formula). ​

Answer 1

Answer:

90√3

Step-by-step explanation:

we know that it is a equilateral triangle with perimeter 180m

so length of each side are equal and it is 60m

now

herons formula is √s(s-a)(s-b)(s-c)

s = 180/2 = 90 m(perimeter/2)

also a=b=c=60m

putting the value in formula we get

area=√90(90-60)(90-60)(90-60)

area=√90x30x30x30

area=90√3

this is the required area
