The perimeter of a rectangle is 98 feet. the raitio of its length to its width is 5:2 find the area of the rectangle

Perimeter is 2 width + 2 length = 98

2 (2x) + 2 (5x) = 98

4x+10x = 98

14x = 98

x = 7

so width = 2*7 = 14 feet

length = 5*7 = 35 feet

then the area of the rectangle is width*length = 14*35 = 490 feet
