Question

Mr Smith wants to put fence around his yard. the dimensions of the yard are 65ft by 32ft . the fencing is sold in whole meters. how much should he buy? round to the nearest meter

Answer 1

The perimeter of the yard is 59.13 meters, round it to the next whole number, so he needs to buy 60 meters of fence.

Explanation:

Answer 2

To determine how much fence is needed to fence the yard, you have to calculate the perimeter of the yard.

The yard is rectangular with dimensions 65ft by 32ft. To calculate the perimeter you have to add twice the length and twice the width:

`\begin{gathered} P=2l+2w \\ P=2\cdot65+2\cdot32 \\ P=130+64 \\ P=194ft \end{gathered}`

The perimeter of the yard is 194ft.

Next, you have to express the perimeter in meters to determine how much fence he must buy.

1foot = 0.3048meters

To express the result in meters you have to multiply it by 0.3048:

`194\cdot0.3048=59.1312m`

The perimeter of the yard is 59.13 meters, round it to the next whole number, so he needs to buy 60 meters of fence.
