Answer 1

Step-by-step explanation:

Equable means A figure whose perimeter and Area is NUMERICALLY equal

( 4.5 + 3.6 ) * 2 = 8.1 * 2 = 16.2 = perimeter

4.5 * 3.6 = 16.2 = area

So fig a is equable

area of triangle = 1/2 * 6 * 4 = 12

side = 5+5+6 = 16

so its not equable

in 12th Ques, use all the Values for y and check
