Question

The yearbook staff enlarges a picture with a length of 5 inches and a width of 7

Answer 1

present dimensions = 5*7

dimensions after scaling with factor 3 = 15*21

dimensions after reducing by scale factor 0.5 = 7.5*10.5

area of rectangle = length * breadth

so area of yearbook = 7.5*10.5 = 78.75

because, 78.75<80

so, the yearbook will fit in area of 80 inches^2

Answer 2

I believe yes, the area of the picture is 78.75 square inches. hope this helps you
