The area of a triangle is 42 square centimeters, the bottom is 12 decimeters, how high is it

The area of a triangle is 42 square centimeters, the bottom is 12 decimeters, how high is it


12 decimeters = 120 cm
42 × 2 △ 120 = 0.7 cm



The area of the triangle is 42 square decimeters, the bottom is 12 decimeters, and the height is 40______ Decimeter


The height of this triangle is 7 decimeters, so the answer is: 7



The area of a triangle is 84 square centimeters, the height is 0.4 decimeters, how much is the bottom


84 times 2 divided by 4cm = 42cm



In a 10 cm long, 7 cm wide rectangle, you can put at most______ A circle with a radius of one centimeter


If the radius is 1 cm, the diameter is 2 cm, 10 △ 2 = 5 (pieces) 7 △ 2 ≈ 3 (pieces) 5 × 3 = 15 (pieces). Answer: at most 15 circles with a radius of 1 cm can be placed. So the answer is: 15



In a 10 cm long, 8 cm wide rectangular cardboard draw a largest circle, the diameter and radius of the circle is how many centimeters


Diameter of circle = 8 cm
Radius = 4 cm



In a 10 cm long, 8 cm wide rectangular cardboard draw a largest circle, then the diameter and radius of the circle is how many centimeters?


Diameter 10 radius 4



A triangle and a parallelogram have the same base and height. The difference between their areas is 30 square meters. The area of the triangle is? M2? The area of the parallelogram is? M


Triangle area is 30 square meters, flat quadrilateral is 60 square meters



A triangle and a parallelogram have the same base and height. If the area of the triangle is 30 square meters, then the area of the parallelogram is () square meters


If a triangle and a parallelogram have the same base and height, then the triangle is half the area of the parallelogram
So the area of the parallelogram is (60) square meters
