Question

the perimeter of rectangle is 130 cm if the breadth of rectangle is 30 cm find its length also find its area of rectangle​

Answer 1

hey your answer :-

• Perimeter of rectangle = 2(l + b)
• 130 = 2l + 2×30
• 130 = 2l + 60
• 2l = 130 - 60
• L = 70/2 cm
• => L = 35 cm

1. Area of rectangle = L × B
2. A = 35 × 30
3. A = 1050 cm

Mark as brain list and thanks my all answer..

Answer 2

Let the length of rectangle be L

perimeter of rectangle =2(l+b)

130 =2(L+30)

130= 2L+60

130-60=2L

70=2L

70/2=L=35

Area of rectangle=l×b

=30cm×35cm

=1050²
