To find the area of the shape, you can split the shape into 2 shapes, a rectangle and a triangle. The area of a rectangle is A=l x w and the area of a triangle is A=1/2 bh. The are of the rectangle is 200 since 20 times 10 is 200. The area of the triangle is 20 times 4 divided by 2. The area of the triangle is 40. Add both areas to get the total are of 240. The area of the shape is 240.
Perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.
slope = -2, or -2/1....so flip the slope...-1/2...and change the sign...1/2.
so the perpendicular slope would be 1/2.
