Answer: 1: 1,650 ft squared 2: 113m squared
Step-by-step explanation:
1: For the first problem, you want to split the shape apart into 2 pieces (generally, you want it to be easy to calculate the area of e.g. one long and one squarelike rectangle.) You're on the right track drawing and shading in 2 shapes (long and square-like rectangles). The measurements of the long rectangle are 15 ft and 40 ft, so we multiply them together to get 600 ft squared. Then, we solve for the square-like rectangle by multiplying 30 ft by 35 ft which equals 1,050 ft squared. We then add the 600 ft squared rectangle and the 1,050 ft squared square-like rectangle to get 1,650 ft squared as your answer.
(15×40)+(30×35)=1,650
600+1,050=1,650
2: For the second problem, we just have to do the same thing as the last. We split it into 2 parts again: the long and square-like rectangles. We do 13m times 5m to get 65m squared. Then we do 8m times 6m which equals 48m squared. Then, we add up the 65m squared and 48m squared to get 113m squared as the area.
(13×5)+(8×6)=113
65+48+113
