20. Compute mowing time Problem: A program is required to read from the screen the length and width of a rectangular house block, and the length and width of the rectangular house that has been built on the block. The algorithm should then compute and display the mowing time required to cut the grass around the house, at the rate of two square meters per minute. Work out the algorithm using pseudo code. Rearrange the following lines to suit the requirements. house_area = house_length* house_width Output mowing_time to screen Calculate_mowing_time block_area = block_length* block_width Get house_length, house_width END Get block_length, block_width Prompt operator for block_length, block_width mowing_area = block_area-house_area mowing_time = mowing_area/2 Prompt operator for house_length, house_width Implement the program in Java.

W P Details I am using JES and I have to create an animation using JES. The animation must be at least 5 and at most 10 seconds long, the animation frams rate must be 30 so you will need to create at least 150 frams , the canvas for the animation should be 300-500 pixels in both height and width. The program should use exactly one for loop and they must be at least 3 things in motion in the animation, they must all move differently in a substantial way. other requirements are in the picture. please I need this as soon as possible . Thank you in advance must all move differently in a substantial way. 1. At least one "thing" must be a filled drawing object (i.e., use addArcFilled or addRectFilled or addovalFilled) 2. At least one "thing" must be an image 3. The other "thing" can be anything - other drawing objects, small pictures, whatever but it must be different than object 1 & 2 above. If using a filled object, it must be a different type of object and a different color than used for…
