Question

a triangle has its sides as 13 cm,14 cm and 15 cm . a parallelogram having double the area of this triangle stands on side 14 cm of this triangle then height of parallelogram is ​

Answer 1

Answer:

Given

2*Area of triangle=Area of parallelogram

Step-by-step explanation:

Area of triangle=root of s*s-a*s-b*s-c

s=a+b+c÷2

s=14+13+15÷2

s=21

Area of triangle=root of 21*21-14*21-13*21-15

=84

Area of triangle=Area of parallelogram

2*84=Area of parallelogram

168=Area of parallelogram
