Question

The sum of the length and breadth of a rectangle is 8 cm and the difference is 2
What is its area?​

Answer 1

Answer:

$15 \: cm {}^{2}$

Step-by-step explanation:

let length be a and breadth be b..

So;

a+b=8

a-b=2

Now; add both the equations..

a+b-b+a=8+2

2a=10

a=5cm

Now; 5+b=8

b=8-5

b=3

Area= l×b

= 5×3

= 15 cm^2
