If square ABCD has area 25, and the shape of the longer shaded square is 9 times the area of the smaller shaded square, what is the length of one side of the smaller shaded square?
Well first, what do the lengths of the sides of square ABCD have to be if the area is 25?
awesome now lets make an equation for the size of the smaller square: area of smaller square = x area of bigger square is = y x = y/9 So first we need to think of values that, when squared to = the area, can be dividd by nine and = other possible areas. Can you thinkk of possible ones? remember they have to be less than 5
hey it says the area of the larger shaded is 9 times the are of the smaller shaded so is it |dw:1441120945403:dw|
