Answer:
Step-by-step explanation:
<u>The full surface area is:</u>
- S = Ph + 2B = (3 + 4 + 5)*12 + 2(1/2*3*4) = 144 + 12 = 156 cm²
Correct choice is D
1
This is the correct answer
Answer:
281.25 cm^2
Step-by-step explanation:
Given that,
The scale factor of Two similar triangles = 5:2
Area of the smaller rectangle = 45 cm^2
To find,
The Area of the larger rectangle = ?
Procedure:
As we know, similar triangles have similar ratios of sides. Thus, this can be written in proportion with the sides' ratio to the left while ratio of areas on the right.
(5)^2/(2)^2 = a/45
∵ The area of the larger rectangle = 25/4 * 45
= 281.25 cm^2
Answer:
98x^2-42x+45
