What is the correct answer?

b & d

Step-by-step explanation:

W = 2(5+2y) L = 4(5+2y) so perimeter is 2(5+2y)+4(5+2y) or 6(5+2y) and if multiplied then 30+12y

72 sq. units

Step-by-step explanation:

There are four rectangles of length 8 units and width 2 units, and two squares of length 2 units each.

area of one rectangle=8×2=16 sq. units

area of four rectangles=16×4=64 sq. units

area of on square=2×2=4 sq. units

area of two squares=4×2=8 sq. units

total surface area=64+8=72 sq. units
