Question

Q7. Find the area of an isosceles triangle XYZ in which XY= ZX = 4 cm and YZ = 10cm.

Answer 1

Step-by-step explanation:

xy=4cm

zx=4cm

yz=10cm

meaning:a=4,b=4,c=10cm

SEMI PERIMETER: a+b+c/2

4+4+10/2

18/2=9

Heron`s Formula

root s (s-a)(s-b)(s-c)

root 9(9-4)(9-4)(9-10)

root 9*5*5*-1

root3*3*5*5*-1

let take common

3*5root-1

15root-1

THIS TRIANGLE DOESN'T EXIST BECAUSE THE OTHER TWO SIDES SUM SHOULD BE MORE OR EQUAL TO THE THIRD SIDE..........
