Question

to fence a rectangular from of 750m² 110m of fence has been used calculate the dimension of the form​

Answer 1

Answer:Area of rectangle = L * W = 750 m^2 -----(1)

Perimeter = 2(L + W )

110 = 2(L + W)

55 = L + W

W = 55 - L ------(2)

plug (2) in (1)

L(55 - L) = 750

 

55L - L^2 = 750

L^2 - 55L + 750 =0

(L -30)(L-25)=0

L = 30 or L =25

if L = 3 0 W = 55-30 = 25

if L=25 then W = 55-25 = 30

therefore dimensions of Rectangle are 30m and 25m
