Lol, were are learning the same thing! Anyway, Your answer would be 292.5. It would be this answer because the dotted lines are actually pointing out what the height is and the area of a triangle equals 1/2bh(base x height divided by 2). So knowing this information, you would multiply 13 x 45 and get an answer of 585. Then you would divide it by 2. This leads you back to the original answer of 292.5. I hope I helped! :)

The length of the side sqaure A is 50% OF THE LENGTH OF THE SIDE SQUARE b

UNO [17]

Let's say the side length of square A is x, which means the side length of square B is 2x.

Then, the area of square A can be written as , and the area of square B can be written as .

There's no diagram here with shaded region, so I'll just find the area of square A as a percentage of the area of square B:

= 1/4 = 25%

So, the answer is 25% (note this is the answer to the question: "express the area of square A as a percentage of the area of square B; there is no diagram showing me where the shaded area is, so I cannot answer the original question
