find the base and height of triangle in ratio 8to 5 and area is 320

Answer 1

let ratio 8x:5x
area of triangle=1/2 bh
320=1/2*8x*5x
320=20x*x
x*x=16
x=4
base=8*4=32
height=5*4=20

Answer 2

The height of a triangle, y, varies directly to the base of the triangle, x, so that when the height is 14 ft the base is 7 ft. If the height of a triangle is 10 ft, what would be the base of the triangle?
