Answer:
y²+10z-10y-yz
Reaaranging the terms
=y²-yz+10z-10y

i hop this will help you :)
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
