the two equal sides of an isosceles triangle are taken as y cm and unequal side is taken as x cm.find it perimeter in terms of x and y . Share with your friends Share 1 Varun.Rawat answered this Let ABC be the isosceles ∆.Let AB = AC = y cm and BC = x cmPerimeter of ∆ABC = AB + BC + AC = y+x+y = 2y+x cm 1 View Full Answer Shanza answered this As one of the two equal sides is taken as y cm, we double it to 2y cm. Now, to find the perimeter we need to measure all the sides so, 2y + x = 2yx -2 Rajtilak Sarania answered this zdczs -2 Sampriti Mohanty answered this 2yx 1
