The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape is a rectangle with sides measuring 7cm and 10cm. To find the perimeter, you add up all the sides: 7cm + 7cm + 10cm + 10cm = 34cm. Therefore, the perimeter of this shape is 34cm.
10cm x 7cm x 12cm =840 square cm3
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 10cm * 15cm = 75 square cm. Therefore, the area of the triangle with a base of 10cm and a height of 15cm is 75 square cm.

If the sides are 10cm, 17cm and 21cm, the three angles are approx 28, 53 and 99 degrees. It is an obtuse angled triangle.
