Question

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

Answer 1

peri = 130
2(l+b) =130
2(l + 30) = 130
l +30 =130 /2
l =65-30
l=35 cm
area = l ×b
=35× 30
=1050

Answer 2

Perimeter of rectangle = 2(l+b)=130cm
Breadth = 30cm
2(l+30)=130
2l+60=130
2l=130-60
2l=70
l=70/2
l=35cm
