Trapizoid area formula = (b1+b2)/2×h
rectangle formula =l×w
trapizoid 1: (12+16)/2×5
trapizoid 2: (12+16)/2×5
rectangle: 10×12
solve
t1 + t2:
(12+16)/2×5
28/2×5
14×5=70 +70=
140 ft^2
r: 10×12=120ft^2
140-120=20ft^2 of wood
Answer:
$ 37.5
Step-by-step explanation:
It is given :
Price of the dress in the market = $ 50
The shopkeeper a discount percentage = 25%
Therefore the discount amount is = 25 % of 250

= 12.5
Therefore the sale price of the dress is = 50 - 12.5
= 37.5
Therefore the sale price is $ 37.5
Given statement is "point where the perpendicular bisectors of the three sides of a triangle intersect".
Perpendicular is basically a vertical line that makes 90 degree angle with the base.
bisector means the line which divides side into two equal parts.
So perpendicular bisector in any triangle will be the line which is drawn on the side of the triangle and perpendicular to that side.
Now these perpendicular bisectors meet at some point.
That point is called circumcenter.
Hence final answer will be "circumcenter".
