The base of a triangle is 3 / 2 meters, and its height is 4 / 9 meters. What square meters is its area!
2/3*4/9 8/27
The bottom of a triangle is 16 / 9 decimeters and the height is 8 / 3 decimeters. What is the area of this triangle? How many square decimeters is the area of the parallelogram equal to its base and height
The bottom of a triangle is 16 / 9 decimeters and the height is 8 / 3 decimeters. What is the area of this triangle?
9 / 16 × 8 / 3 = 3 / 2 square decimeter
How many square decimeters is the area of the parallelogram equal to its base and height
3 / 2 × 2 = 3 square decimeter
The area of a triangle is 2 / 9 square decimeters, the height is 4 decimeters, what is the bottom?
Bottom × height Division 2 = area
Low × high = 2 area, i.e. 2 × 2 / 9
Low = (2 × 2 / 9) except high 4
Low is 1 / 9 decimeter
The bottom of a triangle is 6 meters long. If the bottom is extended by 2 meters, the area will be increased by 3 square meters?
3 × 2 △ 2 = 3 (m),
6 × 3 △ 2 = 9 (square meter);
Answer: the original triangle area is 9 square meters
The bottom of a triangle is 6 meters long. If the bottom is extended by 2 meters, the area will be increased by 3 square meters. What is the original area of the triangle
If the bottom is extended by 2 meters, the area will be increased by 3 square meters
Then the height of the triangle
=3×2÷2
=3 (m)
The area of the original triangle
=6×3÷2
=9 (M2)
The bottom of a triangle is 6 meters long. If the bottom is extended by 2 meters, the area will be increased by 3 square meters?
3 × 2 △ 2 = 3 (m),
6 × 3 △ 2 = 9 (square meter);
Answer: the original triangle area is 9 square meters
The area of a triangle is 6 / 5 square meters, the height on one side is nine decimeters, and the length of the side is several decimeters
6 / 5 × 2 △ 9 = 4 / 15 (decimeter)
The area of a triangle is 5 / 6 square meters and the height is 5 decimeters. How many decimeters is its bottom
5 / 6 square meter = 250 / 3 square decimeter
250/3×2÷5
=100 / 3 decimeter
Its bottom is 100 / 3 decimeter
The base length of a triangle is 1 / 2 of a decimeter, equivalent to 1 / 3 of the height. What is the area of this triangle? A story book has 240 Pages. After reading it for 4 days, he has read 2 / 3 of the book. How many pages does he read every day? For two bags of fertilizer, take 1 / 3 from bag a and 3 / 4 from bag B. at this time, the weight of bag a is exactly twice that of bag B. the original fertilizer in bag a is 60kg, and how many kg is the original fertilizer in bag B?
1. Triangle area = 1 / 2 * bottom * height = 1 / 2 × 1 / 2 decimeter × (1 / 2 decimeter △ 1 / 3) = 3 / 8 square decimeter = 3 / 800 square meter
2. Average number of pages read per day = pages read / days used = (240 × 2 / 3) × 4 = 40 (pages / day)
3. The weight of the original fertilizer in bag a is 60 kg, and the remaining is 60 × (1-1 / 3) = 40 kg after taking out 1 / 3 of bag a. the weight of remaining 1 / 4 after taking out 3 / 4 of bag B is 40 ￣ 2 = 20 kg
The area of a triangle is 34 15 square decimeters, its height is 17 Five decimeters. What is the bottom of this triangle?
Thirty-four
15×2÷17
Five
=68
15÷17
Five
=11
3 (decimeter)
A: the bottom of the triangle is 11
Three decimeters
