Question

what is the length of the boundary of a rectangular park of dimensions 50m by 120m​

Answer 1

Answer:

length of boundary = its perimeter

Step-by-step explanation:

so perimeter = sum of all sides

perimeter = length + breadth + length + breadth

take perimeter = length + breadth + length + breadth

take length + breadth common

so

perimeter = (length + breadth) x 2

length = 120 m

breadth = 50 m

perimeter = (120 +50) x 2

perimeter = 170 x 2

perimeter = 340 m
