Answer:

640 cm²

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here the ratio of sides = 5 : 20 = 1 : 4, thus

ratio of areas = 1² : 4² = 1 : 16

The area of ABCD is 16 times the area of EFGH, so

area = 40 × 16 = 640 cm²

Answer:

Step-by-step explanation:

I think its 130. So its asking us to find the area of ABCD.

So it tells us what A and B represent; 20 cm. D and C on the other side

Look similar to the other side. So make that 20cm. Now we don’t know what the

Rest of the sides represent. So the other side B and C looks like it can be 40cm.

Why? It looks double the size of the other side “ A and B, D and C “ now we don’t know what A and D represent. So you can see that A and D have a smaller size than B and C so it cant be 40cm. That side “ A and D “ is not the right size as A and B and D and C. So i think that side “ A and D “ represent 30cm. Therefore the answer is 130cm

Sorry if I’m wrong
