Question 519303: a quadrilateral has four sides. Quadrlateral ABCD has three sides that have equal measures. The measure of the fourth side is 8cm longer than each of teh over sides.

Three sides are equal:
A = B = C
.
The other side is 8 cm longer
D = A+8 = B+8 = C+8
.
Perimeter = 28
.
3A +A+8 = 28
4A +8 = 28
4A = 20
A = 5
so
B = 5
and
C = 5
.
D = 5+8 = 13
.
15+13 = 28
Correct.
.
The sides are 5, 5, 5, and 13 cm.
.
Done.
