Question

If the perimeter of a rectangle
is 124m & the width is 35m,
what is the length?

Answer 1

Let length be x

ATQ

`\\ \sf\longmapsto 2(Length+Width)=124`

`\\ \sf\longmapsto 2(x+35)=124`

`\\ \sf\longmapsto 2x+70=124`

`\\ \sf\longmapsto 2x=124-70`

`\\ \sf\longmapsto 2x=54`

`\\ \sf\longmapsto x=(54)/(2)`

`\\ \sf\longmapsto x=27m`
