Construct a right triangle inside a rectangle ABCD where point A is the vertex of the triangle, another vertex lies on AB, another vertex lies on CD, and the hypotenuse is the square root of 13

i think the answer is 90 hope this

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
