Question

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​

Answer 1

Answer:

P of squares =

square 1:   4x

square2:     4(2x+1)

                =8x+4

4x+8x+4=100

12x=100-4

12x=96

x=96/12=8

side of bigger square= {2(8) +1}

                                = ( 16+1)  = 17cm

Area= 17 x 17

       =289 cm2
