Question

3. The perimeter of a rectangle is 230 cm. If the length of the rectangle is 70 cm, find its breadth and area.​

Answer 1

Answer:

breadth = 45cm

area= 3150cm sq

Step-by-step explanation:

perimeter of rectangle= 2(l+b) =230

length given 70

2(70+b)=230

70+b=230/2

70+b=115

b=115-70

b=45

area of rectangle = l×b

70×45 = 3150 cm sq
