Question

if altitude of an equilateral triangle is 10 root 3 find its area and perimeter​

Answer 1

Answer:

area is 100√3

perimeter is 60

Step-by-step explanation:

we know in equilateral triangle angel are same and thay are 60

so we have altitude is 10√3

so tan60=10√3/(x/2)

x=20

so area is = 1/2 (base) (hight)

= 1/2( 20)(10√3)

= 100√3

perimeter is 20+20+2=60
