Answer 1

Answer:

Given, a rectangle with perimeter =130 cm and breadth =30 cm.

We know that, perimeter of a rectangle =2(length + breadth)

Perimeter of the rectangle =130 cm

⇒   2×(length + breadth)=130 cm

⇒   length +30=1302

⇒   length +30=65

⇒   length =65−30=35 cm

Now, area of rectangle = length × breadth

=35×30

=1050 cm2

Thus, the length and the area of the rectangle are 35 cm and 1050 cm2 respectively.

Answer 2

Answer:

Length= 30cm

Area= 1050cm²

Step-by-step explanation:

the perimeter of a rectangle=2×(l+b)

130cm= 2×(l+35)

130cm= 2l+70

2l=130-70

2l=60cm

l=60/2

l=30

Area of a rectangle= l×b

30×35

=1050cm²
