Step-by-step explanation: for the height just add 3 cm until you reach the top, which will give you 15 cm
for the amount just count them and for the top top layer count up to 9, which will give you 25 triangles.

x = 10
The perimeter of an object is found by adding all of the sides. The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet. Adding these together we get a total length of 7 feet. However, he may want to use a slightly longer board to account for any errors!
