Answer 2

Answer:

Answer

Given, the area of a rectangular field is 48m

2

and one side of the rectangle is = 6m.

Therefore, area of a rectangle = length×breadth

⇒ 48 = 6×breadth

⇒ Breadth = 8 m

In triangle ACD, ∠D=90

= 36+64

⇒ (AC)= \sqrt{100} $$ = 10 m

Time taken at the rate of 20 m/ min = distance/ speed

= 10/20 =
