Hey ,
Here is the answer to ur question...
Given: A triangle in which area =144root3 cm^2....
To find: Perimeter of the triangle...
Solution: As we know area of an equilateral triangle =root3/4 a^2.....
and given area is 144root3
=>Area =144root3
=>root3/4a^2=144root3
=>a^2=144root3*4/root3
=>a^2=144*4
=>a^2=576
=>a=root576
=>a=24
So,now we got each side of the triangle as 24cm.
=>perimeter=side*3=24*3=72cm....
Hope this helps u....

The complete question in the attached figure
we know that
[Area of her bedroom]=[11*10]+[12*8/2]+[10*6]------> 218 ft²
the answer Part A) is
Are needed 218 ft² of carpeting for the room
[perimeter of her bedroom]=[11+10+11]+[12]+[6+10+6]+[8]-------> 74 ft
the answer Part B) is
Are needed 74 ft <span>of baseboards</span> for the room
