What is the lcm of 15, 20and35

420

Step-by-step explanation:

List all the factors

15 = 3 • 5

20 = 22 • 5

35 = 5 • 7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
