what- Suppose the side lengths of a triangle have the ratio 5:12:13. Some possible triangles are shown here. Now suppose the perimeter of the triangle is ninety centimeters.What are the side lengths?
Given that the perimeter of the triangle is 90 centimeters, we can determine the actual side lengths by multiplying the ratio by a common factor. The total ratio value is 5 + 12 + 13 = 30. To find the actual side lengths, we divide the perimeter by this total ratio value: 90 / 30 = 3. Therefore, the side lengths of the triangle are 5 x 3 = 15 cm, 12 x 3 = 36 cm, and 13 x 3 = 39 cm.
A rectangle has whole number side lengths and an area of 81cm² what dimentions could it have?
It could be 1 cm by 81 cm, 3 cm by 27 cm, 9 cm by 9 cm, 27 cm by 3 cm, or 81 cm by 1 cm.
What is the perimeter of asqare if it is 3cm in length?
A square has 4 sides of equal length The perimeter is the sum of the lengths of the four sides each side has length 3 cm 3+3+3+3 = 12 cm perimeter

Is it possible to build a triangle with the lengths of 3 cm 4 cm and 5cm?
Oh, what a happy little question! Yes, it is possible to build a triangle with sides of 3 cm, 4 cm, and 5 cm. This special triangle is called a right triangle, and it follows the Pythagorean theorem where the square of the longest side (5 cm) is equal to the sum of the squares of the other two sides (3 cm and 4 cm). So go ahead and paint that lovely triangle with confidence!
What Are The Length Of The Side Of The Smaller Triangle if The Similarity ratio Of Two Quadrilaterals Is 4 3. If The Sides Of The Lengths Of The Larger Quadrilateral Are 12 cm 16 cm And 10 cm?
A quadrilateral with only the lengths of three sides given is not uniquely specified and so the question has no answer.

How many 30-cm lengths can be cut from a 3-meter length?
1m = 100 cm so 3m = 300 cm300 cm/60 cm = 5 lengths.
What is the slant height of a pyramid that has all sides as equilateral triangles with sides of length of 9 cm and the surface area of the pyramid is 140.4 square cm?
The surface area of the pyramid is superfluous to calculating the slant height as the slant height is the height of the triangular side of the pyramid which can be worked out using Pythagoras on the side lengths of the equilateral triangle: side² = height² + (½side)² → height² = side² - ¼side² → height² = (1 - ¼)side² → height² = ¾side² → height = (√3)/2 side → slant height = (√3)/2 × 9cm = 4.5 × √3 cm ≈ 7.8 cm. ---------------------------- However, the surface area can be used as a check: 140.4 cm² ÷ (½ × 9 cm × 7.8 cm) = 140.4 cm² ÷ 35.1 cm² = 4 So the pyramid comprises 4 equilateral triangles - one for the base and 3 for the sides; it is a tetrahedron.
How can you find side lengths of a right triangle using 3 degree measures of 27 90 and 63 and only one side length with 13 cm?
You can find relative lengths (compared to each other), but not absolute ones (what they actually are).
How do you classify a triangle with 3 given side lengths?
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
