Answer 2

Step-by-step explanation:

समबाहू त्रिभुज का परिमाप = 3a

वर्ग का परिमाप = 4a

according to question ,

3a = 4a - 20

4a - 3a = 20

a = 20m

समबाहू त्रिभुज का परिमाप = 3(20) = 60m.

भुजा (a) = 20m

वर्ग का परिमाप = 4(20) = 80m

भुजा(a) = 20m

त्रिभुज की भुजा : वर्ग की भुजा

6a : 7a

120 : 140

वर्ग का क्षेत्रफल = (भुजा)²

= 140*140

= 19600m²
