53.5 square cm to 1 d.p.
Use the cosine rule to find an angle.
Then use: Area = 1/2*a*b*sin C
The area of rectangle is : 168.0
Area is 98cm2
Since there are five numbers given it is assumed that the figure in question is a pentagon. Unfortunately, a triangle is the only polygonal shape that is rigid. A pentagon, with all five sides of known lengths is not rigid - it can be flexed in the same way that a square can be flexed into a rhombus. The area of a rhombus can take any value from 0 up to the value of the square: the exact value is indeterminate. Similarly for a pentagon.
The area of triangle is : 18.0
The area of a triangle is (base)x(height)x1/2.So, we put in your values (base=19, height=14) and we get 19x14x1/2=19x7=133.The area of a triangle with a base of 19cm and a height of 14cm is 133.
The area of rectangle is : 168.0
Area is 98cm2
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
A square with a side length of 14cm has an area of 196cm2
The area of triangle is : 56.0

30 square cm because it's a right angle triangle
The area of triangle is : 18.0
this is 5cm (:
