Answer:
1800 m²
Step-by-step explanation:
The surface area of a prism is the sum of the areas of its faces.
⇒ Surface area of rectangle prism = 2(LH) + 2(BH) + 2(LB)
⇒ Surface area of rectangle prism = 2(LH) + 2(BH) + 2(LB) = 450 m²
⇒ 2(LH + BH + LB) = 450 m²
<u>Finding the surface area if the dimensions are doubled:</u>
⇒ 2[(2L × 2H) + (2B × 2H) + (2L × 2B)]
⇒ 2[(4LH) + (4BH) + (4LB)]
⇒ 2[4LH + 4BH + 4LB]
⇒ 2[4(LH + BH + LB)]
⇒ 2[2 × 2(LH + BH + LB)]
⇒ 2[2(450)] [2(LH + BH + LB) = 450 m²]
⇒ 2[900]
⇒ 1800 m² (Option C)
Answer:
9 meters
Step-by-step explanation:
Area of a square:
There are only 2 variables in this equation, and as A is already given, you can solve for s. Just plug in the given value and go from there:
You cannot have a negative side length, so the answer here is just 9 meters.
Yes they can. they can have any lengths
2. All real numbers greater than 0
All you have to do is to make (6’0) x=6. And y=-8 (0’8) on the graph
