Question

the answer is 54 units but how pls solve my question​

Answer 1

answer: 63 units

Step-by-step explanation:

area of 6 congruent squares(full fig)=54

=> area of one square= 54

6

=> area of one square= 9 sq. units

therefore,

(side)^2 = 9

side= √9

therefore,

side = 3 units

perimeter of the given figure= 21 × side

= 21 × 3

= 63 units
