Question

The perimeter of ractangle is 130 cm if the breath of ractangle is 30 cm. Find its length. Also find the area of the ractangle?

Answer 1

We know that perimeter of a rectangle = 2(l + b).

Given that breadth of the rectangle = 30cm.

Given that perimeter of a rectangle = 130cm.

2(l + b) = 130

2(l + 30) = 130

2l + 60 = 130

2l = 70

l = 35cm.

We Know that Area of a rectangle = l * b

                                                          = 35 * 30

                                                          = 1050cm

Answer 2

Breadth =35cm
Area=l*b=30*35=1050cm^2

Answer 3

✍️perimeter of rectangle = 2(l + b )

130 = 2(l + b )

if b = 30

putt the value of b

2(l + 30)=130

2l + 60 =130

2l = 130 - 60

l= 70/2

l = 35cm✔️✔️

✳️Area of rectangle = l × b

l × b = 30 × 35

= 1050 cm^2✔️✔️
