If you notice there are 4 small right triangles, one at each corner of the shape. There are 2 small rectangles, one on the top and one on the bottom. There is 1 big rectangle sitting in the middle.
One trick we can do to calculate the area faster is instead of saying 4 small triangles, we can say there are 2 small squares. The reason we can do this is because all the triangles have a base length of 2 and a height of 2 also. If we put two triangles together they form a rectangle or square, but in this case it forms a square. Now let's find the area of each of the small parts: small square, small rectangle, and big rectangle. Remember: Area of rectangle = length x width.
Area of 1 small square (made of two small triangles): It has a length of 2 units and a height of 2 units so each square's area is, 2 x 2 = 4 square units Area of 1 small rectangle: It has a width of 2 units and a length of 6 units. The rectangle's area is 2 x 6 = 12 square units Area of big rectangle: It has a width of 6 units and a length of 8 units. This means the big rectangle's area is 6 x 8 = 48 square units. To find the area of the whole figure we add up all the small parts.
Area of 1 small square: 4 square units Area of 1 small rectangle: 12 square units Area of 1 big rectangle: 48 square units. Note: We have 2 small squares, 2 small rectangles, and 1 big rectangle.
Total area of whole figure = 2(area of small square) + 2(area of small rectangle) + 1(area of big rectangle)
Well out of 100 jelly beans 24 are black so it would be a 24 out of 100 chance to pick a black jelly bean. But that can be simplified down to a 6 out of 25 chance. So your answer is 6/25. Hope this helped. ;)
70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.
