Yes. To prove it, note that if they satisfy A2 + B2 = C2 then they can form a right triangle. Well, 32=9 and 42=16 and 52=25 and 9+16=25 . So 3, 4, and 5 do in fact work fine. In high-school geometry, this kind of triangle has a special name. It's called a "Three four five right triangle". Duh.
It is: 0.5*6*3 = 9 square meters
This is not the question I was looking for.1Record the length and width of a square or rectangle. Substitute your measurements into the formula "length x width" to solve for area. For example, a rectangle with a length of 7 meters (m) and a width of 3m has an area of: 7m x 3m = 21m^2 (21 meters squared, or 21 square meters).2Use the formula "(base x height)/2" to find the area of a triangle. A triangle with a height of 7m and a base of 3m has an area of 7m x 3m = 21m^2, divided by two equals 10.5m^2.
3 x 7 sq m
area parallelogram = length of side x height between parallel sides ⇒ 33.75 m2 = side x 3m ⇒ side = 33.75 m2 ÷ 3m = 11.25 m
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has a length of 7 meters and a width of 3 meters. To find the perimeter, you would add the lengths of all sides: 7m + 7m + 3m + 3m = 20 meters. Therefore, the perimeter of a rectangle with dimensions 7m x 3m is 20 meters.
It is not possible to answer the question. There are three measures, but they cannot form a 2D shape - a triangle. If they are the lengths of sides of a solid figure, there is no information as to what shape that figure is - a cuboid or a parallelepiped.
Every one of them could be a side of a rectangle. It is not possible to give an answer in respect of an unspecified rectangular object. however, i feel the question is incorrect as it should be sides of the triangle and according to it 3rd is the answer as 3+5<9 :)
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.
It is a linear equation in one variable, m. Although the question did not ask for a solution, here it is 3m + 23 = 6m - 4 Subtract 3m from both sides: 23 = 3m - 4 Add 4 to both sides: 27 = 3m Divide both sides by 3: 9 = m
5m+3=3m+9 First get the ms and the constants on separate sides. Do this by subtracting 3 from both sides (5m=3m+6) Then subtract 3m from both sides (2m=6) then divide both sides by 2 to find m. (m=3)
3m - 12 = -6 Add 12 to both sides, so m is by itself: 3m = 6 Now divide both sides by 3 to find the answer: m = 2
3m+4 = 6m-48 3m-6m = -48-4 -3m = -52 Divide both sides of the equation by -3 to find the value of m remembering that a - divided into a - is equal to a +: m = 17 and 1/3 Or can just not devide both sides with -3 , cuz when you put -3 on the other side, you'll get -52 divided to 3 and get to the answer of -17.33(3) :D Cheers !
Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
3 meters. 9m2/3m Divide both sides by 1m 9m/3 Simplify 3m
It is a linear equation in one variable. It can be solved for m, as follows: -3m - 4 = 2 Change all signs: 3m + 4 = -2 Subtract 4 from both sides: 3m = -6 Divide both sides by 3: m = -2
The equation for the area of a triangle is 1/2 x B x h where B = base and h = height. So the area of a triangle with B = 11m and h = 3m is 16.5m
