Question

27. The area of a rectangle is 35 cm2 and its length is 7 cm. Find the perimeter of the rectangle​

Answer 1

Answer: 24 cm

For this, first we need to find the breadth.

Breadth= Area/Length

= 35/7 = 5 cm

Now perimeter of rectangle= 2(l+b)

= 2(7+5) = 2*12 = 24 cm

Answer 2

to find the perimeter of the rectangle

We have to find the breadth of the rectangle firstly.

length = 7cm

l×b = 35cm²

7cm×b = 35cm²

b = 35cm²/7cm

b = 5cm

perimeter = 2×(l+b)

= 2×(5+7)cm

= 2×12 cm

= 24 cm

the perimeter of the rectangle is 24 cm

hope it helps.
