Question

The width of a rectangle is three fourth its length .If the perimeter is 210m .Find the dimensions of the rectangle.

Answer 1

Answer:

Length = 60 m, Width = 45 m

Step-by-step explanation:

Let the length = x

Let the width = 3/4x

A. T. Q.

Perimeter =2( L + B)

210 m =2(x + 3/4x)

210/2 m = 7/4x

105 ÷ 7/4 = x

105 * 4/7 = x

60 = x

So, length = 60 m

width = 3/4 * 60 = 45 m

Answer 2

Step-by-step explanation:

Let the length of the rectangle be x.

breadth=3x/4

Perimeter=2(l+b) = 210

2(x+(3x/4))=210

x+(3x/4)=210/2=105

(4x/4)+(3x/4)=105

7x/4=105

7x=105×4=420

x=420/7=60

length=x=60

breadth=3x/4=3(60)/4=180/4=45
