Question

Rectangle ABCD has vertices A(15, 18), B(−5, 3), C(1, −5), and D(21, 10).

Answer 1

Answer:

1. 25

2. 10

3. 250

Step-by-step explanation:

Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()²  + ()²  

1. LENGTH OF AB :

A = 15,18

B = -5,3

√ (-5 - 15)²  + (3 - 18)²  

= √ 400 + 225

= 25

2. LENGTH OF AD :

A = 15,18

D = 21,10

√ (21 - 15)²  + (10 - 18)²  

= √36 + 64

= 10

AREA :

A=w x l

10 x25 = 250
