Question

johans garden is 32 m long and 15 m wide .if he uses 2 layers of barbed wire ,to fence the garden ,what is the total length of the wire used
plz step by step

Answer 1

Step-by-step explanation:

length= 32 m

breadth= I5 m

Perimeter = 2(I + b)

= 2( 32+ 15)

= 2 (47) = 94 m

length of wire of 2 layers of wire = 94x2 = 188 m

Answer 2

Answer:

length of garden = 32 m

breadth of garden = 15 m

we will the perimeter of the garden because we have to find the wire length surrounding the garden

so perimeter garden

2(L+B) = 2(32m+15m) = 2x47m = 94 m

now we know the length of the barbed wire 1 time surrounding the garden, to find the barbed wire surrounding the garden 2 times we will multiply the perimeter of the garden by 2

so, 94 x 2 = 188 m

the length of the barbed wire is 188 m
