The side length should be 7 because 7*7=49 and the area of a rectangle is A=length*width
Radius of design= 18 in
Area of design= pi*r^2
= 3.14*324
= 1017.36 sq. in
1017.36/144
= 7.065 sq. ft
7.065*35
= 247.275
Therefore, the cost of building the design costs $247.275 to make
Answer:
3.√
4.√
Step-by-step explanation:
similar rectangles have proportional sides so compare corresponding sides to check
1. 169/1.3 = 49/0.7 → 130 ≠70 no
2. 18.55/5.3 = 10.5/3.5 → 3.5 ≠ 3 no
3. 120/24 = 60/12 → 5 = 5 yes
4. 189/2.1 = 81/0.9 → 90 = 90 yes
