Question

the perimeter of an isosceles triangle is 14 centimetre is lateral side and the base are in the ratio of 5 is to 4 then the area of the triangle is ​

Answer 1

Step-by-step explanation:

5x+5x+4x = 14

then 14x= 14

and x = 1

then s = a+b+c/2 = 5+4+5/2 = 7

and area = √7(7-5)(7-4)(7-7)

=√7×2×2×3

= 2√21

or 2×4.5 = 9 square cm.
