Question

The parameter of a rectangular is 130 cm if the breadth of a rectangular is 30 cm find its length also find the area of the rectangular

Answer 1

Answer:

Perimeter=130

Perimeter=2(l+b)

Perimeter=2(l+30)=130

=2l+60 =130

=2l=130-60=70

2l=70

l=70÷2=35cm

Area=l x b

Area=30x35

=1050 sqcm

Answer 2

Answer:

length of rectangular plot is 35 cm.

area of rectangular plot is 1050 cm²

Step-by-step explanation:

Perimeter of rectangle = 2(L+B)

=> 2(L+B) = 130

=> 2(L+30) = 130

=> 2L + 60 = 130

=> 2L = 130 - 60

=> 2L = 70

=> L = 70/2

=> L = 35 m

Therefore, length of rectangular plot is 35 cm.

Now,

Area of rectangle = L × B

=> Area of rectangular plot = 30 × 35

=> Area of rectangular plot = 1050 cm²

Therefore, area of rectangular plot is 1050 cm²
