What is the area of a 5cm by 7cm rectangle?
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 7cm and the width is 5cm. So, the area of the rectangle is 7cm x 5cm = 35 square centimeters.
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

The perimeter of a square is 52 cm Find the length of its each side and also its area?
Oh, what a lovely problem to solve! Since the perimeter of the square is 52 cm, we can divide that by 4 to find the length of each side, which is 13 cm. To find the area of the square, we simply square the length of one side, so the area is 169 square cm. It's wonderful to see how math can help us discover the beauty in shapes!
Find the width of a rectangle if the length is 7cm and perimeter is 35cm?
The width is 10.5 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
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
