Question

one of the two equal sides of an isosceles triangle is 5.4 CM. if the perimeter of the triangle is 15.4 cm, find the length of the remaining sides of the triangle.​

Answer 1

ANSWER IS 4.6



Since the triangle is isosceles then two sides will be equal
Perimeter =length +length+ length
Since the two sides are equal then

P=5.4+5.4+L=15.4

10.8+L=15.4
L=15.4-10.8
L=4.6

Answer 2

4.6cm

Explanation:

5.4 is the length of one side and if you have 2 sides that are equal you double that

5.4 x 2 = 10.8

15.4 - 10.8 = 4.6cm
