Answer:
450
Step-by-step explanation:
If the perimeter is 90 inches then each side must equal 30 inches. To find the area of a triangle you mulptiply the base by the height and divide by 2. The base is 30 and the height is 30. 30*30=900. 900/2=450.
m=y+7x, or m=7x+y, it is correct either way you would write it.
