${\huge\sf{\orange{\underline{\blue{\underline{❥︎A᭄ɴsᴡᴇʀ࿐}}}}}}$

Sangeetha,425m

Step-by-step explanation:

Perimeter Of Square = 4xSide

4x135m

540m

Perimeter of Rectangle=2(L+B)

2(75m+40m)

115m

Difference=

540m-115m

425m

Sangeetha Cover more distance by 425m

Answer 2

Answer:

sangeetha runs faster

Step-by-step explanation:

Sangeetha,

Perimeter of square park =  4 x side
                                  =  4 x 135
                                  =  540m  

Rimpy,

Perimeter of rectangular park =  2( l + b )
                                                  =  2( 75 + 40 )
                                                  =  2 x 115
                                                  = 230

Difference =  540 - 230
                  = 310m

∴ Sangeetha covers more distance by 310m
