Question

A rectangular picture has a width that is 2 times wider than its length. The area of the frame is 50 square inches. What are the dimensions of the frame?

Answer 1

Dimensions of the frame is a fancy way of saying fill in Width x Length = Area

We know that Width = 2 x Length

Plug in Width into the Area formula to find Length

(2 x Length) x Length = 50

2 x Length² = 50

Length² = 25

Length = 5

Take that and plug it in for Width

Width = 2 x 5 = 10

Dimensions in terms of Width x Length is 10 in x 5 in
