Question

The corresponding sides of two similar rectangles are 6 ft and 10 ft. The area of the smaller rectangle is 78 ft2. To the nearest whole number, what is the area of the larger rectangle?

Answer 1

area of a rectangle is A = LW
you are given one side of a small rectangle, and the area of that rectangle, so you can solve for the other side

then use the ratio to determine the other side of the larger rectangle

then use A = LW on the larger rectangle to find the area
