1 trapezoid with an area of 280cm2. If you extend the bottom of the baby to 2 sides and add 10cm and 5cm, we get a rectangle with an area of 400cm2. Find the length of the two sides of the trapezoid

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
