Question

Marcia will make a frame for her picture. The picture frame will be three times as long as it is wide. The width of the frame will be 4 inches. How much wood does Marcia need for the frame

Answer 1

Marcia needs 32 inches of wood for the frame

Explanation:

we know that

The perimeter of the rectangular frame is given by the formula

`P=2(L+W)`

we have

`W=4\ in`

`L=3W`

substitute the value of W

`L=3(4)=12\ in`

Find the perimeter

`P=2(12+4)=32\ in`
