Question

the measure of the sides of a triangle are 13cm, 13cm and 10cm find the Area of this triangle find the length of altitude on the side of length 10cm ​

Answer 1

1/2×13×10=5×13=65cm^2 I hope it will help

Answer 2

side=13cm,13cm,10cm

if you draw perpendicular to 10cm

then it becomes a right triangle

by Pythagoras theorem

13sq=5sq +xsq
169=25+xsq
169-25=xsq
144=xsq
X=12
altitude is 12
area=12×10×1/2
=60cmsq
