Answer 1

Hey Mate
your answer is here

let length = w cm
breadth = 7 cm
so,
Area = w×7
w = 63/7 = 9 cm

and,
perimeter = 2(w+7) = 2(9+7)= 2×16 = 32 cm

Answer 2

Hello,

Your answer ➡️

We have to find the length of given rectangle.

(a) Let the length of rectangle be x cm.
and
Given,
area = 63 cm ^2
breadth = 7 cm.

Now,

We know that,

Area of rectangle = length × breadth
63cm^2 = x × 7
63 / 7 = x
9 cm = x.
So,

Length = 9 cm.

Now,
(b) We have to find perimeter,
Perimeter = 2(l + b )
perimeter = 2(9 + 7 )
perimeter= 2 × 16
perimeter = 32 cm.

So,

(a) 9 cm.
(b)32 cm.

Hope it helps you.
