Question

the perimeter of a rectangle is 230 cm. if the length of a rectangle is 70 cm find its breath and area.
​

Answer 1

Answer:

The breadth is 45 cm.

The area is 3150 cm².

Step-by-step explanation:

The length is given as 70 cm.

Perimeter of rectangle = 2(l+b)

                        230 cm = 2(70+b)

                                115 = 70+b

                                   b = 115-70 = 45 cm

Area = lxb = 70x45 = 3150 cm²

Hope this helps!

Answer 2

Answer:

perimeter=2(length+breadth)

230 =2(70+b)

230/2=70+b

115=70+b

b=115-70

b=45cm

and area=l×b

=70×45

=3150cm^2
