25^2=7^2 + x^2
49 + x^2 = 625
x^2= 576
square both sides
x=24
area of rectangle = l×b
So, area of drawing = l×b = 8cm×4cm = 32cm²
The value is already in its simplest form, it cannot be reduced any further.
Do Pythagorean theorem. If you don't know what that is...
Do A squared plus B squared Equals C squared and you will get your answer for the shape. Then calculate the area
