Question

The diagram shows a small rectangular field. If Linda runs from A to B to D to C to A, how far does she run?

Answer 1

Answer:

Option 2

160m

Step-by-step explanation:

First we have to find the hypotenuse of a triangle BAD

since it forms a right angle triangle

let us apply this formula

(BD) =√ (AB)^2 +(AD)^2

then BD i.e., Diagonal of rectangle = hypotenuse of triangle

then BD = 50 m

so complete distance is AB+BD+DC+CA

= 30+50+30+50

160 m

Answer 2

Answer:

140m

Step-by-step explanation:

The perimeter of that rectangle = 2(40 + 30) m = 2 x 70 m = 140 m
