The area of a triangle is 578 square centimeters. Its base is four times the length of its height. Find the height and base of the triangle.

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.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
