Answer:
ΔABD ≅ ΔACD by SAS, therefore;
by CPCTC
Step-by-step explanation:
The two column proof is presented as follows;
Statement Reason
ABCD is a trapezoid Given
Given
Definition of a trapezoid
ABCD is an isosceles trapezoid Left and right leg are equal
∠BAD ≅ ∠CDA Base angle of an isosceles trapezoid are congruent
Reflexive property
ΔABD ≅ ΔACD By SAS rule of congruency
CPCTC
CPCTC; Congruent Parts of Congruent Triangles are Congruent
SAS; Side Angle Side rule of congruency

Answer:
- perimeter: 22 1/30 m
- area: 29 m²
Step-by-step explanation:
The perimeter is given by the formula ...
P = 2(L+W)
P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)
P = 22 1/30 . . . . meters
__
The area is given by the formula ...
A = LW
A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters
The perimeter is 22 1/30 meters; the area is 29 square meters.
