Answer 1

mark it as brainliest

Answer 2

perimeter = 120m

breadth = 25m

so, perimeter = 2 (length + breadth)

or, perimeter = 2length + 2breadth

or, 2lenght = perimeter - 2breadth

or; lenght = perimeter - 2readth/2

or, length = $\frac{120 - (2 \times 25)}{2}$

or lenght = 35

therefore; lenght = 35 meter..
