Answer:
AREA OF THE TRIANGLE = 9CM
Step-by-step explanation:
isosceles triangle has 2 equal sides.
therefore,
AB = 10CM
BC = 10CM
AC = 4 CM (Base - Given)
Area of a triangle = 1/2 × base × height. - (1)
TO FIND HEIGHT
= 1/2 × 4 × h
= 4×2+1/2 =h
h = 4.5
therefore HEIGHT = 4.5
USING THE FORMULA (1)
= 1/2 × B × H
= 1/2 × 4 × 4.5
= 2 × 4.5
= 9
