Question

half the perimeteeof a rectangl e garden, whose lengthis four meter more than its width is 36 meter. find the dimension of the garden

Answer 1

Heya !
_____

__________________________________________________

◼Let the breadth of the garden be x m

◼Then , it's length becomes ( x + 4 ) m


=> Perimeter of a rectangle = 2 × ( L + B )

•°• According to the given condition , we have -

=> ½ × 2 ( L + B ) = 36

=> ½ × 2 ( x + x + 4 ) = 36

=> 2x + 4 = 36

=> 2x = 32

=> x = 16

◾Breadth of Garden - x = 16 m

◾Length of Garden - (x+4) = 20 m

✔ Dimensions are 16 and 20 m respectively !!

Answer 2

perimeter is 2(l+b)
so half will be l + b = 36
and l - b = 4

on solving these we get
l = 20 m
and b = 16 m
