Answer: 117cm^2

Step-by-step explanation:

Arectangle = L*W

= 54cm^2

Atrapezoid = 1/2 (a+b) (h)

= 1/2 (15+6) (6)

= 1/2 (21) (6)

= 1/2 (126)

= 63cm^2

Answer:

a. $A_{trapezoid}=228ft^2$

b. $A_{trapezoid}=228ft^2$

c. They are equivalent

Step-by-step explanation:

a. The trapezoid can be divided into two triangles and one rectangle. For the three figures, the height is 12ft. For the rectangle, the dimensions are 12ftx10ft. Since the legs are of the same length the triangles have a base of 9ft (because the rectangle takes 10 feet from the base of 28 feet and there are 18 feet left over, these 18 are divided equally between the two triangles).

$A_{rectangle}=bh=(10)(12)=120ft^2$

$A_{triangle}=\frac{bh}{2}=\frac{9(12)}{2}=\frac{108}{2}=54ft^2$

$A_{trapezoid}=A_{rectangle}+A_{triangle}+A_{triangle}\\Area=120+54+54=228ft^2$

b. The formula is

$A=h(\frac{B+b}{2})=12(\frac{10+28}{2})=12(19)=228ft^2$

c. They are equivalent

What transformation will take triangle GBC onto triangle ABC?<br><br> plz help it’s due today

umka2103 [35]

Answer:

Reflection of ΔGBC on side BC.

Step-by-step explanation:

Transformation is the process by which the orientation or dimension of a given shape or figure is adjusted by some method of processes to produce an image with a required property.

From the given diagram, triangles ABC and GBC are congruent, so that;

AC ≅ GC

AB ≅ GB

BC is a common side to both triangles

Therefore, the appropriate transformation that would take ΔGBC onto ΔABC is reflection on side BC.
