Answer:
25
Step-by-step explanation:
4.5×5.5=24.75
so 24.75 is the area of the room but you have to buy whole tiles so you would need to but 25 tiles
You use the slope formula, (y2-y1/x2-x1)
Anything over 90 and bellow 180 degrees is a obtuse.
Answer:
yes because angle 1 and 5 are congruent
Lets say the base is x and the height is y. The new base would be 1.2x and the new height would be 1.3y
Area of a triangle is base times height divided by 2:
1.2x*1.3y/2 = (1.2*1.3 + x*y)/2 = 1.56xy/2 = 0.78xy = 78% of xy
But a normal area would be 50% of xy
78% - 50% = 38%
ANSWER: 38% increase
