2. 578=l^2/2
3. 1156=l^2
4. Aftr square root l=24

Answer 2

Answer: Length of rectangle = 17 meters.

Step-by-step explanation:

As per the given statement,

2×length(L) = breadth(B)        .......(i)

Area = 578 sq meters

We know that,

Area of Rectangle = Length × Breadth

So,

Area = L× (2×L)                            .......from(i)

578 = 2 L²

289= L²

L=√289

L=17 meters.
