Answer:
30.96 m²
Step-by-step explanation:
In white there are four parts of a circle, so we can split the 12 m in half to show the radius, and then solve to find the area of the full circle.
A = r²
a = (6)²
a = (36)
a = 113.04
Then you find the area of the whole box.
12 x 12 = 144
Then you subtract the area of the circle in white from the area of the whole box.
144 - 113.04 = 30.96 m²
So that’s the area of the shaded region.
Ok so pete lays 10 more than jim per hour
pete and jim laid same amount of tiles
j=jim's rate
p=pete's rate
6j=5p
but pete lays 10 tile per hour faster so
p=10+j
sub
6j=5(10+j)
6j=50+5j
minus 5j both sides
j=50
jim can lay at 50 tiles per hour
7/25, 6/25, and 11/50. Looks like they are already in order, or you meant to do that...
