Step-by-step explanation:
area of triangle =1/2×base×height
base=8cm
height=6cm
so, area will be = 1/2×8×6
= 1×8×3
=24cm.

Answer:
Step-by-step explanation:
In an isosceles triangle, the altitude (height) is the perpendicular bisector of the base, forming a right angle with the base and dividing it into two equal parts. Therefore, half the base, the altitude, and the leg form a right triangle. (This is depicted in the attachment below.)
Since a²+b²=c² (let a=height of the triangle):
a²+4²=6²
a²=20
a=
h=
h=2
The area of a triangle=bh
Area=(8cm)(cm)
Area=8cm²
