Question

Each of the two sides of a square measures (8a - 7) units and (3a +13) units, respectively. The area of the square is _____.

Answer 1

Step-by-step explanation:

firstly, equate both sides to have value of 'a'

8a - 7 = 3a + 13

5a = 20

a = 4

so, sides : 8a - 7 = 25 and 3a + 13 = 25

now, area = (25)^2

= 625 sq.unit
