Question

If the area of trapezium is 52cm² and parallel sides are 12cm and 14cm and non parallel sides are equal. Find its perimeter.
Please Help Me!!!!

Answer 1

Answer:

26+2root20

Step-by-step explanation:

area of trapezium = 1\2 (sum of llel side × height

52=1/2 (12+14)×h

52×2/26=h

4=h

perimeter = sum of ll sides + non ll sides

h^2=b^2+p^2

h^2=4^2+2^2

h^2=16+4

h^2= 20

h= 20root

so perimeter = 14+12+20root+20 root

= 26+2root 20
