Answer:
Area of shape B = 312.5 cm²
Step-by-step explanation:
Ratio of Area of A : Area of B = 12² : 15²
Given that area of A is 200 cm², let the area of shape B = x
Therefore:
200:x = 12²:15²
200/x = 144/225
Cross multiply
144x = 200*225
144x = 45,000
x = 45,000/144
x = 312.5 cm²
Area of shape B = 312.5 cm²
The square root of 64 is 8 and the square root of 100 is 10.... so,
square root of 64/100 = 8/10
8/10 reduces to 4/5
Answer D.
Angle 2 is 180-127=53 degrees
