X+y=130 or y = 130-x
So 2.5x+ 1.75 (130-x)= 265
5/2x +7/4{130-x}=265
10x + 910-7x=1060
3x = 1060-910
3x=150
X= 150/3 =50
So square blocks are 50
Rectangular blocks are 80
So 2.5x+ 1.75 (130-x)= 265
5/2x +7/4{130-x}=265
10x + 910-7x=1060
3x = 1060-910
3x=150
X= 150/3 =50
So square blocks are 50
Rectangular blocks are 80
