Question

the side of rectangular park are is the ratio 4:3 If its area is 1728m Findnits8 perimeter

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

Ratio of Length : Breadth = 4 : 3 (Given)

Define x:

Let x be the constant ratio:

Ratio of Length : Breadth = 4x : 3x

Solve x:

Area = Length x Breadth

1728 = (4x)(3x)

1728 = 12x²

x² = 1728 ÷ 12

x² = 144

x = √144

x = 12 m

Find the dimension:

Length = 4x = 4(12) = 48 m

Breadth = 3x = 3(12) = 36 m

Find the Perimeter:

Perimeter = 2(Length + Breadth)

Perimeter = 2(48 + 36)  = 168 m

Answer: The perimeter is 168 m
