Reuben wants to have an amount of $40,000.00 in 16 years' time when she retires. She can invest her money at a simple interest rate of 5.5% per annum. How much money ( to the nearest dollar) should she invest now to achieve her aim?

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.
