Question

AOBC is a rectangle whose three vertices are A(0,-3),O(0,0),B(4,0).the length of it's diagonal is

Answer 1

Answer:

Step-by-step explanation:

Since quad. AOBC is a Rectangle ,Both the diagnols are equal in length.

Hence AB=OC

Now,By distance formula

AB=$\sqrt{(4-0)^2 +(0+3)^2}$

AB=$\sqrt{16+9}$

AB=$\sqrt{25}$=±5,But length is a non negative quantiity,hence AB=5 UNITS
