Question

A square and an isosceles triangle have the same perimeter.the base of the isosocles triangle is equal to 12 cm and each side of square is 5 cm shorter than each of the equal sides of the isosceles triangle .find the perimeter of square

Answer 1

Answer:

first find the perimeter of isosocles triangle

perimeter of isosocles triangle is 29

so perimeter of square is also 29

Answer 2

Answer:

44

Step-by-step explanation:

let side of triangle be x

therefore side of square will be (x - 5)

Now

12 + 2x = 4(x - 5)

12 + 20 = 4x - 2x

x = 16

now perimeter of square is

4(16 - 5) = 4(11) = 44 cm..
