What is the area of a triangle that is 8 cm 13 cm 7 cm?
What is the are for a rectangle of 13cm and 7cm
What is the perimeter of a square with one side that is 7cm?
Perimeter = 4*7 = 28 cm
What is the length of missing side b in the triangle 7cm and 13 cm?
It might be pythagoras therom but it can only be Pythagoras when the traingle has a right angle. If it does then try to work it out using phythagoras. If the angle between the given sides is B, then: b2 = a2 + c2 - 2ac cos B ⇒ b2 = (7 cm)2 + (13 cm)2 - 2 x 7 cm x 13 cm x cos B ⇒ b = √(218 - 182 cos B) cm If it is a right angle triangle, with B the right angle, cos B = cos 90o = 0 and this becomes Pythagoras making the side: b = √218 cm ≈ 14.76 cm If there is a right angle, not between the 7 cm and 13 cm, then the 13cm side is the hypotenuse (as the hypotenuse must be the longest side) and the other side is: b = √(132 - 72) cm = √120 cm ≈ 10.95 cm
What is the side length of a cube with a volume of 343 cubic centimeters?
7 cm(7cm x 7 cm x 7cm) = 343 cm3
A triangle has sides of 7cm and 9cm What is one length for the 3rd side?
The third side can have any value in the range (2 cm, 16 cm).
A triangle has two sides that have lengths of 8 cm and 14 cm what lengths could not represent the length of the third side?
7cm
What is the triangles area if the sides are 7cm 7cm and 5cm?
A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
The perimeter of a square is 52 cm Find the length of its each side and also its area?
A square has four equal sides. So the side length is 13 cm. The area, 13 cm x 13 cm, is 169 square centimetres.
What is the area of a rectangle that has a width of 7cm and a length of 4 cm?
It is: 4*7 = 28 square cm
What is the height if a box of staples is 6cm in length 7cm in width 378 cm cubed in volume?
9 cm
If the sides of a square are lengthened by 7cm the area becomes 256cm2 find the length of a side of the oringial square?
256 = 162; 16 - 7 = 9 cm
Find the width of a rectangle if the length is 7cm and perimeter is 35cm?
The width is 10.5 cm.
What the length missing of the triagle shape 7cm and 13 cm?
you have to do 7 squared + 13 squared = x squared. 7 squared is 49 + 13 squared which is 169. 169+49=x squared. 218= x squared. The square root of 218 is about 14.765. So the answer should be about 15cm if the missing side is the hypotnus (the diaganal side)
What is the length of the longest side of a right angled triangle if the two shorter side are 5cm and 12 cm?
13 cm
What could be the length of the third side of a triangle that has two sides of lengths 13 cm and 29 cm?
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the side of length 29 cm is the longest side then the missing side must be greater than 29 cm - 13 cm = 16 cm If the missing side is the longest side then the missing side must be less than 29 cm + 13 cm = 42 cm Thus any length that is greater than 16 cm and less than 42 cm. Examples include: 17 cm, 18 cm, 20 cm, 36 cm, 41cm
