Answer:
A
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b
Then the ratio of their areas is a² : b²
Hence
ratio of sides = 2 : 9, then
ratio of areas = 2² : 9² = 4 : 81 → A
Answer:
a = 3
Step-by-step explanation:
1) Simplify 5a - 9 + a to 6a - 9.
2) Add 9 to both sides.
3) Simplify 9 + 9 to 18.
4) Divide both sides by 6.
5) Simplify 18/6 to 3.
Therefor, the answer is, a = 3.

Answer:
376 inches^2
Step-by-step explanation:
<h3>1. Divide up each type of rectangle </h3>
- 10x6
- 6x8
- 8x10
<h3>2. Find the area of each rectangle</h3>
- 10x6=60
- 6x8=48
- 8x10=80
<h3>3. Multiply each rectangle by two to get the opposite one</h3>
- 60x2=120
- 48x2=96
- 80x2=160
<h3>4. Add them together</h3>
120+96+160=376
The surface area is 376 inches^2
