Question

The area of a rectangular field is 96m2. Te length of one side is 12m. The farmer needs to know its perimeter to work out how much fencing will be needed

Answer 1

Area (rectagular field)=side₁ x side₂
Area=96 m²
side₁=12 m

96 m²=12 m* side₂
side₂=96 m²/12m=8m.

Perímeter (rectangular field)=2*side₁+2*side₂
Perimeter (rectangular field)=2*12 m+2*8 m=24 m+16 m=40 m.

Answer: he needs 40 m of fencing.
