A quilt design is made up of right triangles that have a base of 6 inches and a height of 2 2/3 inches. If the quilt is rectangular with dimensions of 90 inches by 72 inches, how many triangles are needed to complete the quilt?​

810

Step-by-step explanation:

number of triangles needed = area of rectangle / area of triangle

area of triangle  = 1/2 x base x height

1/2 x 6 x 8/3 = 8

area of rectangle = length x width = 90 x 72

90 x 72/ 8 = 810
