The sides of triangle are 18cm,18cm,28cm.This triangle is converted into square.what is area of square?

• perimeter of the triangle= 18+18+28=64cm
  perimeter of the triangle=perimeter of the square=64cm
  in case of square 4*side=perimeter so, 4*side=64 =>side=16cm
  now area of the square is side^2 so, area=16*16= 256 sq cm.

• 256sq cm
  triangle perimeter = 64
  sqr each side = 64/4 = 16
  area of square = 256

• formula is [(a+b+c)/4]^2

• ans. 64sqcm
  add all the sides of the triangle to get its perimeter..
  therefore, 18+18+28=64
  then divide (64/4)=16cm..(since,4 of the sides of a square are equal)
  area of a square= (side)^2 =(16)^2= 64sq.cm

• area of the sq=((18+18+28)/4)^2=256

• 64/4=16^2=256

• 18+18+28=64
  64=4a^2
  64/4=16
  a^2=16 ==> a=4

• answer is 256 .total length of the traiangle is a+b+c.so when it s converted into square total length will be perimeter 4a.through that we ll get a.then squaring a will be the answer
