How many different two-digit numbers can be formed using the digits 1, 3, 4, and 5. repetition of digits is allowed. a.8 ways b.12 ways c.16 ways d.20 ways

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.

good luck on your studies! : )
