Question

45. Two squares have sides x cm and (2x+1) cm,
respectively. The sum of their perimeters is
100 cm. Area (in cm²) of the bigger square is
(a) 225
(b) 289
(c) 64
(d) 81​

Answer 1

Step-by-step explanation:

given

sides of square is x and [(2x+1)

perimeter of square is 100

100= 4(x) + 4(2x+1)

100= 4(x+ 2x +1 )

100= 4 (3x+ 1)

25= 3x+1

24= 3x

x= 6

one square side is 8and it's area is 64

and other square side is 【2x+1】is 17

and it's area is 289
