Answer 2

Answer:

These are some examples:-

Explanation:

a : b = 2 : 3 , b : c = 4 : 5 , c : d = 6 : 7 . Find a : b : c : d.

Given a:b=2:3,b:c=4:5,c:d=6:7

a:b=2×8:3×8=16:24

b:c=4×6:5×6=24:30

c:d=6×5:7×5=30:35

soa:b:c:d=16:24:30:35

If A(2,−1), B(3,4), C(−2,3) and D(−3,−2) be four points in a coordinate plane, show that ABCD is a rhombus but not a square. Find the area of the rhombus.
