Question

if each side of triangle is increased by ten percent then find the increase in area of the triangle​

Answer 1

Step-by-step explanation:

If only one side is increased then the area will increase by 10%. If all the sides are increased, the area will become

(1+.1)^2 = 1.21 so the area increases by 21%.

Answer 2

Step-by-step explanation:

(1+1+1)/2=S=1.5

Area of triangle is √S(S-1)(S-1)(S-1)=0.4330

If one side is increased by 10% and other sides remain same

(1.1+1+1)/2= S =1.55

Area of triangle is

√1.55(1.55–1.1)(1.55–1)(1.55–1)=0.4593

Increase % is 4593*100/4330=106–100=6
