Question

a farmer had a plot of land measuring 14 m by 10m. the farmer put a fence, leaving a margin 1m wide all around it. find the length of the fence.​

Answer 1

Dear Student,

◆ Answer -

56 m

● Explaination -

We have to keep 1 m margin on each side of land plot, so

Length of fence rectangle = 1 + 14 + 1 = 16 m

Width of fence rectangle = 1 + 10 + 1 = 12 m

Now length of total wire used for fence will be perimeter of fence rectangle.

Perimeter = 2 (length + width)

Perimeter = 2 (16 + 12)

Perimeter = 2 × 28

Perimeter = 56 m

Therefore, wire of 56 m length will be required for fence.

Thanks dear...
