An after school meeting of the math club lasted 1.5 hours, 2/3 of this time was taken up by a discussion on the history of fractions. the remaining time was spent doing on problem solving. how much time did the math club spend on problems?

they are simplified

step-by-step explanation:

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.
