The sum of two numbers is 21. The second number is six times the first number. Work out the two numbers. Write your answer on one line

Step-by-step explanation:

a +B=21 B=6a a+6a=21 7a=21  a=21:7 a=3 b=6x3 b=18

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.
