Answer:
315 cm²
Step-by-step explanation:
Given the scale factor of 2 similar figures is a : b , then
ratio of areas = a² : b²
Here the scale factor = 7 : 21 = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the area of the enlargement is 9 times the original, so
area of enlargement = 35 × 9 = 315 cm²
188cm^2
or 188 centimeters squared
just make sure to put the exponent of 2 at the end
Answer:
11.98
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 53 = x/15
15 sin 53 = x
11.97953265 = x

Answer:
Work backwards to solve this problem.
If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.
