Question

find the length and area of the rectangle if breadth = 30 cm perimeter = 130 cm​

Answer 1

Answer:

length=25cm

area=750cm²

Explanation:

130=2(l+30)

65=l+30

length=65-30=25cm

area=25×30=750cm²

Answer 2

Answer:

Perimeter of rectangle=130cm

2(l+b)=130cm

2(l+30)=130cm

2L=130-60cm

2L=70

L=35cm.

areas = L ×b

=35× 30

b=1050 cm
