IF you have three straight sticks of lengths 5cm 12cm 19cm Can you arrange these sticks into a triangle?
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.
Each of the equal sides of an isosceles triangle is 5 cm greater than the base. The perimeter is 46 Centimeters. What is the length of each side of the triangle?
a is one of the equal sides of the iscosceles triangle b is the base perimeter is a + a + b = 46cm a = b + 5cm subsitute a for b + 5cm in the perimeter equation b + 5cm + b + 5cm + b = 46cm This simplifies down to 3b + 10cm = 46cm subtract 10cm from both sides of the equation 3b + 10cm - 10cm = 46cm - 10cm 3b = 36cm Then divide each side of the equation by 3 3b ÷ 3 = 36cm ÷ 3 b = 12cm Subsitute b back into a = b +5cm a = 12cm + 5cm a = 17cm So you have 2 sided with the length of 17cm and the base with the length of 12cm
What is the area of a triangle with 5cm and 7cm?
1/2*5*7 = 17.5 square cm * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.

Calculate area of a triangle?
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
What is the area of the triangle if it is 13cm 12cm and 5cm in length?
30 sq cm ((12 x 5)/2)
Is a 5cm by 12cm a right triangle?
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
