Answer:
1. BC = 24
Perimeter of ABCD = 96
3. PT = 9
ST = 7
Explanation:
Question 1
All the side lengths of a rhombus are equal.
Therefore, BC = AB = 24
So the perimeter of ABCD = 24 × 4 = 96
Question 3
The diagonals of a rhombus bisect each other at right angles.
Bisect means to divide into two equal parts.
Therefore, PT = TR so PT = PR ÷ 2
As PR = 18 then PT = 18 ÷ 2 = 9
QT = ST so ST = QS ÷ 2
As QS = 14 then ST = 14 ÷ 2 = 7
