A rectangular board is 40cm by 16cm. An L-shape of uniform width is cut from it. If the remaining area is 340cm^2, find the width of the L-shape.

Question

anonymous · Answer

First find out the area of the L shape that is by subtracting the remaining area from the total area, Once you have that, split the L shape into two rectangles. See if you can do it now

anonymous · Answer

but the two rectangles would not be identical.. ones longer than the other.. i think we have to use quadratic equations to solve.. but idk how. :/
