Question

18. The area of a plot is 6000 sq. metres.
If the ratio of its length and breadth
is 12:5, then find the length of its
diagonal​

Answer 1

Step-by-step explanation:

let ratios be x.

ratio=12:5 (given)

length=12x breadth=5x

area of the plot = 6000m²

Length X Breadth =6000

12x X 5x = 6000

60x² = 6000

x² = 6000

60

x² = 100

x = √100

x = 10

length = 12(10) = 120m

breadth = 5(10) = 50m

By Pythagoras theorem,

B=50m P=120m

H²=B²+P²

H²=(50)²+(120)²

H²=2500+14400

H²=16900

H=√16900

H=130m
