Question

Find the area of the rectangular plot

Answer 1

Answer:

area of rectangle is

2(l+b)

2(4x+3x)=140

8x+6x=140

14x=140

x=140/14

x=10

Answer 2

Answer:

Area is 1200 cm^2

Step-by-step explanation:

As length and breadth are in ratio= 4:3

Let the length is 4x and

breadth is 3x

Preimeter of Rectangle= 2(length+breadth)

140    =   2 (4x+3x)

140     =   2 (7x)

140/2      =    7x

x = 70/7

x=10

Length= 4x = 4×10 = 40 cm
Breadth= 3x = 3×10 = 30 cm

Area = Length × Breadth

Area = 40×30

Area = 1200 cm²
