Question

bettys garden is 80m long and 25m wide and is in the from of a rectangle. if he uses 4 layer of wire to fence the garden what is the total length of wire used? also find the area of the garden

Answer 1

Answer:

840m of wire needed and area is 2000sq.m

Step-by-step explanation:

Perimeter (P) = 2(l+b)

Length (l) = 80m

Breadth (b) = 25m

P = 2(80+25)

  = 210m

4x210 is the length of wire needed to fence the garden

Therefore 840m of wire is needed.

Area = lb

        = 80 x 25

        = 2000 sq.m
