Question

The base of an isosceles triangle having the base 16 cm. If its perimeter is 36 cm, find the
area.​

Answer 1

Answer:

24

Step-by-step explanation:

base =16

triangle is isosceles

perimeter =36

so another 2 sides =36--16=20/2=10

1 side is 10 cm

then draw a perpendicular bisector to base

so base of 1 triangle =8

by Pythagoras theorum 10 square--8square=perpendicular square

100--64=36

so length of perpendicular is 6

so area =half ×8×6=4×6=24
