Question

The perimeter of rectangle is 230cm if the lengh of rectangle is 70cm find its breath and area​

Answer 1

Answer:

perimeter of rectangle =2(l+b)

230=2(70+b)

115=70+b

b=45

so area =70*45=3150

Answer 2

first,we find the breadth of rectangle:

Perimeter = 2(length+breadth)

230 = 2(70+breadth)

230 = 140+breadth

230-140= breadth

90cm = breadth

Now, we find the area of rectangle:

Length × breadth = Area

70 × 90 = 6300cm square.
