Question

This was given to me during a summative test and the teacher didn't bother giving me the correction. I just cannot figure it out

Answer 1

• Base be y

ATQ

`\\ \sf\longmapsto xy=6050\dots 1`

`\\ \sf\longmapsto 2(x+y)=220\implies x+y=110\dots 2`

Now

`\\ \sf\longmapsto (x+y)^2=x^2+y^2+2xy`

`\\ \sf\longmapsto 110^2-2(6050)=x^2+y^2`

`\\ \sf\longmapsto 12100-12100=x^2+y^2`

`\\ \sf\longmapsto x^2+y^2=0\dots(3)`

From all equations

`\\ \sf\longmapsto (x-y)^2=x^2+y^2-2xy`

`\\ \sf\longmapsto (x-y)^2=0-2(6050)`

`\\ \sf\longmapsto (x-y)^2=-12100`

`\\ \sf\longmapsto (x-y)=110\dots(4)`

Now

Adding 3 and 4

`\\ \sf\longmapsto 2x=220`

`\\ \sf\longmapsto x=110m`

One side won't be covered hence

• y=2(110)=220m
