Question

The length of a rectangle is 7 less than 3 times its width. The perimeter of the rectangle is 50 find the width length and area of the rectangle

Answer 1

since the perimeter is 50, we have that

`2w+2(3w-7)=50`
`8w=50+14=64`

then w=8

then the widht of the rectangle is 8 and the lenghth is 3(8)-7=17

and the area is 8(17)=136
