Question

c) The area of a rectangle is 70 cm and it is 7 m broad. (i) Find its length (ii) Find its perimeter ​

Answer 1

Answer:

34cm

Step-by-step explanation:

$Solution,\\\\Area=70cm^{2} \\\\Breadth(b)=7cm\\\\Now,\\\\Length=\frac{Area}{Breadth}\\\\Length=\frac{70cm^{2} }{7cm} \\\\Length=10cm\\\\Again,\\\\Perimeter=2(l+b)\\\\Perimeter=2(10cm+7cm)\\\\Perimeter=34cm$

Answer 2

Answer:

Step-by-step explanation:

solution;

here

area=70

breadth=7cm

now,let length be x.

area=l*b

70=l*7cm

or,70/7=l

10=length

now ,

ii)soln ;

here,

perimeter=2(l+b)

              =2(10+7)cm

               =2*17cm

                =34cm
