+1245 A picture frame consists of two rectangular strips of wood, each having a width of 1 inch on all sides. If the area of the inner light gray strip is 100 , then compute the area of the outer dark gray strip in square inches.
+129852 Notice that we have four corner rectangles in the darker strip, each with dimensions of 2 x 1 = 2 unit^2
So....the total area of these = 8 units^2
The other parts of the dark gray strip would be rectangles with the same dimensions as the rectangles comprising the area of the lighter gray strip...so...their total areas = 100
So...the area of the darker gray strip = 100 + 8 = 108 sq units
Corrected answer !!!
