WILL GIVE BRANLIEST What are the side lengths of square 4 and square 5 in terms of a and b? Do the two squares have the same area? Then, write an expression for the area of square 4 by combining the areas of the four triangles and the two squares. Also, Write an expression for the area of square 5 by combining the areas of the four triangles and the one square. Since the areas of square 4 and square 5 are the same, set the two expressions equal.

sorry i don't know

Step-by-step explanation:

Step-by-step explanation:

square has four triangles and 2 smaller squares. The area of each triangle is the same: ab/2. The are of the smaller square is (bb) an the are of the larger square is (aa). So the total area of square 4 is: 4 times the area of triangle  + aa + bb

do this for both

hope this helps.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
